What Color Garage Door Spring Do I Need
Sectional Garage Door Extension Springs
On this page, y'all tin learn more near extension springs, determine which replacement extension springs you need, and see how to order springs. These springs are for sectional garage doors. If you have a garage door that does not bend as it rolls upwardly into the horizontal tracks, if it is 1 rigid piece that pivots, go to our Ane-Piece Garage Door Extension Springs page.
Exclusive garage doors are hinged, and they bend in the tracks equally the door opens and closes. Many of these doors are balanced with extension springs, also designated "stretch springs," and they have vii characteristics. The length is the measurement of all the coils pressed together. This, along with the inside diameter of the coils and wire size - the thickness of the wire from which the springs are made - make up one's mind the stretch, the distance the spring is extended - normally one-half the door elevation, and pull, the force the spring pulls when stretched its normal length. The type of ends determine how the ends of the spring are mounted. The initial tension is the pct of pull needed to split up the coils. This is determined by the pitch with which the springs are wound. On exclusive garage door springs, this normally is xv percentage. For instance, a 100-pound pull leap requires 15 pounds of weight to split the coils; when a door is open, the two springs will support 15 pounds of door weight without whatever stretch.
Nigh extension springs are made of oil tempered wire. These are usually coated or painted. Some springs are made of galvanized wire.
Extension Spring Counterbalance
Garage door extension springs weigh the weight of garage doors to brand them easy to open and close. I end is secured to a stationary angle or bracket, and the weight of the door pulls the other end.
When a garage door is open most of the door weight is stored in the horizontal tracks. The door volition stay open without extra support because the initial tension of the springs counterbalances the weight of the door. Extension springs are stretched with cables and pulleys. One end of the cablevision attaches to the bottom of the door; the other end of the cable is usually secured to the horizontal track angle with an southward-hook. Equally the door closes, one terminate of the cablevision follows the bottom of the door; the remainder of the cable runs over the pulleys above the door, onto the horizontal rails angle where it is normally secured with a cablevision prune and an south-hook. (For demonstration purposes, the spring is extended from the ceiling, but it is normally suspended from the rear rail hang.)
On the 100 pound door in our example higher up, in that location is one extension spring for each side of the door. Each spring pulls 100 pounds on the pulley, merely the cable on the bottom of the door lifts only 50 pounds. This is because only one-half the tension from the spring is transferred to the door; the other half of the spring tension is transferred to the other cease of the cable, where it is secured to the horizontal track angle with a cable clip and an due south-hook. Equally a upshot, the 100-pound door in our example needs a 100-pound pull jump on each side of the door. Find besides that the spring stretches from 25" to 67 inches. This divergence of 42 inches - one-half the door height - is the spring stretch.
This spring would exist designated 25-42-100 because it is 25" long, it stretches 42" across the 25" length, and the 100 is for the 100 pounds of pull on each leap. Thus, for a seven-foot high garage door that weighs 100 pounds, the door would require two of these 100-pound pull springs.
Temporary Fixes for Cleaved Bound Ends
Quite often, the loop breaks off the end of an extension spring. There are ii options for fixing the jump without replacing it, or for making your door operational until springs can be ordered. Ane is to separate the last ii coils with a screwdriver and attach the s-claw or eye commodities.
The other temporary ready is to install a clip at the end of the spring. Y'all can purchase these at our extension spring hardware folio. Bear in heed that these are temporary fixes. You can expect your bound to break again at the other cease or some other identify along the length of the spring. The only reliable repair is to replace both or all iv springs.
It is important that you replace your sometime extension springs with new springs that volition properly match your door weight. This will provide you with a properly counterbalanced garage door, i that will stay on the flooring when it is closed, stay halfway, and stay up when you open the door. The blog is written for torsion springs, just testing the balance of a door is the same for both systems. Broken pulleys and cables frequently accompany broken extension springs, then you may have a slightly bigger project on your easily that you anticipate.
Making Measurements
At that place are three of import pieces of data that you will need to get in order to select the proper springs for your garage door. These are the door pinnacle, the spring length without the loops, and the door weight. If you can identify the manufacturer and model number y'all may not need to counterbalance the door. Just click the "Find by Model Number" tab below.
One method for weighing a xvi' or wider door is to slide your calibration under the terminate of the door on the side that has a broken jump. Heighten the other side to the same meridian and then support information technology to continue the door level.
The door weight tin be difficult to calculate. You must utilize an analog scale, as about digital scales exercise not respond to changes in the door weight acquired by the door binding in the tracks. If you have two broken extension springs, slide an analog scale under the center of the door to get the total weight. If one of your 2 extension springs is broken, yous can slide the scale under the door under the side with the broken spring as pictured to go half the weight.
Shake the door and cheque each of the rollers for bounden. If one spring is cleaved, the weight you read off the calibration at the cleaved will exist 1/2 the door weight. If you lot accept a full of two springs on your door, and if both springs are broken, the scale will read the total door weight. For more than data, encounter the first five steps of our Extension Spring Replacement tutorial.
If you have a total of 4 springs on your door with two springs on each side of your door, open the door, remove the second spring on the side with the cleaved bound, and lower the door onto the calibration on the side that had the broken spring. With both springs off on this side, you can double this weight to determine your total door weight. It is important to note, however, that since you tin can't weigh the door at the very end, you volition need to arrange your weight to factor in the distance from the finish. For example, if the eye of your scale is 12" from the very end, you will need to add together to the weight your calibration shows. A pct determined past dividing 16' by 15' arrives at 106.66% per centum. Hence a weight of 100 pounds 10 106.66% = 107 pounds. Double this, and the full estimated door weight should be around 214 pounds. This door would utilize two 210 pound lift extension springs. Or, if the door has four extension springs, the door would employ two 100 pound lift springs and two 110 pound lift springs.
A more accurate method for weighing either a torsion spring door or an extension spring door is on our YouTube channel.
The door superlative also helps to make up one's mind which springs you need. For instance, the extension springs made for xiv' high doors are intended to stretch twice as far as the springs made for 7' high doors. As a result, the united nations-stretched length of an extension spring by and large increases as the door height increases.
Another measurement you will need to brand is the un-stretched bound length, not including the ends. Extension springs tend to stretch over time, and then you will demand to remove the spring from the door and shrink the coils when measuring the length. You may need to insert a shaft in the middle of the spring to keep it straight while compressing the coils. Some springs are ruptured so desperately yous may need to measure out and count coils to calculate the length.
While the door manufacture has standardized on bound lengths, there are multiple spring lengths for some of the more than common door heights.
If you lot make up one's mind to purchase an extension spring with a shorter un-stretched length than your quondam spring, y'all will demand to adjust your cables. There volition need to be 2" of additional length for every inch that your new leap is shorter than the quondam spring. If your cables are not adaptable or are also curt, y'all will either demand to replace the cables or order a longer spring. If you lot demand a spring with dimensions not listed in our parts catalog, we can social club a custom spring. These mostly cost near 50% more than our standard springs, so it is probably ameliorate to change the cables instead.
If your new spring is longer than your old spring, you volition need to suit the cables to shorten the pull. Sometimes this requires mounting the Southward-hook on the new springs closer to the garage door.
It is also helpful to examine your leap for color codes. The lifts for extension springs follow these colors:
- Tan - 100#, 200# & 300#
- White - 110#, 210# & 310#
- Light-green - 120#, 220# & 320#
- Yellow - 130#, 230# & 330#
- Blue - twoscore#, 140# & 240#
- Cerise - 50#, 150# & 250#
- Brown - threescore#, 160# & 260#
- Orange - 70#, 170# & 270#
- Gold - 80#, 180# & 280#
- Light Blue - 90#, 190# & 290#.
This pattern is repeated through all the lifts.
Types of Extension Jump Ends
From front end to back: Open up ends, double-loop ends, and clipped ends. There are three types of ends on extension springs, and each of the springs has its own advantages and disadvantages.
Open up looped ends are the easiest to replace. You will not need to open up the eye-bolt, and y'all will not demand to disassemble the pulley. One disadvantage, though, is that the whole jump relies on an open wire at the end. If this is the simply part of your bound that breaks, you may be able to salvage a few dollars and sometimes if you put a clip on the cease of the spring as we show in a higher place.
Double looped ends are more sturdy than open up loops, every bit there are two coils of the spring that connect to the middle-bolt and the caster. One disadvantage, though, is that they accept longer to supercede.
Clipped ends are even more than durable than double loops. The spring clips put less stress on the spring ends to help lengthen the life of the bound, these come standard on extension springs for doors that weigh 200 pounds or more. The disadvantage, though, is that they can be more than difficult to replace.
Replace 1 Spring or Ii?
Nosotros recommend that you replace all of the extension springs on your door. As the springs fatigue, they loosen and do not provide equally much elevator as the new spring. If y'all only supercede 1 of two springs, the door may open unevenly and cause problems such as binding or rollers coming out of the tracks.
Cables & Pulleys
Worn pulleys can crusade problems, and it is skilful to replace them while you are changing your extension springs.
Extension leap pulleys wear out frequently, and sometimes they need to be replaced at the aforementioned fourth dimension as the springs. We highly advise that you check the status of your four pulleys. Since each caster on your door experiences about the same amount of clothing each time the door opens, we propose that you lot replace all iv of your pulleys if you find one that is worn. This will besides save y'all time in the futurity, and it will save on shipping costs.
Extension spring cables wear out very often with the springs. If you examine your cables right now, you may non see whatever bug. Many times, though, the cablevision is frayed or worn in the cable clip, and the cables need to be replaced. This is something to consider when looking to purchase new extension springs.
If i of your cables is frayed or rusted, we advise that you replace both cables. This might salve you problem in the future. The length of cablevision needed determines the prices for the cables for other door heights.
Safety cables are critical to accept on extension spring doors. You lot typically will not need to supercede these cables, but if yous practice not have them, yous should consider purchasing them. The cables run through the length of the jump and contain the pieces of the spring when it breaks. These protect people from injury or death, and they protect cars and other valuable items from beingness damaged when the spring breaks.
All of these parts and more than tin can exist purchased on our extension leap hardware folio. See our how to order department below for help purchasing your extension springs.
How to Guild Springs
Observe beneath the 2 tabs for selecting extension springs.
Club by Door Weight. If y'all know your door weight, click the "Observe by Door Weight" tab. You will so select the number of springs on your door, the door height, the spring length, and the door weight. You'll notice that the menu provides lifts in 10-pound increments. If your door falls between two-door weights, select the lower weight. For example, if your door weighs 168 pounds, select two of the 160-pound lift springs. It's ameliorate to go under than over so the door stays downward when closed and upwards when opened; stronger is non better. The cable and pulley system limits the corporeality of adjustment if the springs are too strong for the door.
Later y'all click "Get!" a new page will appear with upwardly to 3 options for leap ends: open loops, closed double loops, and clips. You lot'll also see the spring part number, length without the end loops or clips, the spring weight, and the lift or pull of each bound. You'll also see the unit toll of each spring. If you accept more than ane door, yous can save on the price of the springs likewise as on the shipping cost. If a long life leap is available, it will appear beneath the offset pick or options above.
Next, yous tin can and then click the part number for more data, and then click "Add together to Cart." Or, you can only click the "Buy" button and so follow links to purchase the springs.
Order by Model Number. Most of the newer garage doors have identifying stickers that designate the manufacturer and model number. If you have this data, click the "Notice by Model Number" tab.
You will then enter the manufacturer, model number, door dimensions, and additional information to help you order the correct springs. Click "Become!"
Later on you click "Get!" a new page will appear with up to three options for spring ends: open loops, closed double loops, and clips. Y'all'll too see the spring part number, length without the cease loops or clips, the spring weight, and the lift or pull of each spring. You lot'll also come across the unit toll of each spring. If you have more than one door, y'all tin can save on the price of the springs likewise as on the shipping cost. If a long life spring is available, it will appear beneath the outset option or options to a higher place.
Next, you can then click the part number for more information, and then click "Add to Cart." Or, you lot can simply click the "Buy" push button and then follow links to purchase the springs.
Long life extension springs similar the one on the right final about three times longer than the 1 on the left.
Longer Life Extension Springs are now available. In our tests hither at DDM Garage Doors, Inc. we have constitute that the standard bicycle life springs get-go to gap at just over 7,000 cycles. These will unremarkably work beyond 10,000 cycles, just only after additional gapping or until the spring breaks. We also found that at this betoken, the springs are gapped an extra inch or so. Three problems occur as a effect of springs gapping.
Extension springs oft fatigue earlier they intermission. Others just intermission without warning. The spring on the left has fatigued and stretched at 10,000 cycles; the one on the right is a long life spring that broke after 28,000 cycles.
One is that the springs lift about 10% less. On a 200 pound door that is about 20 pounds, and if the opener forcefulness is properly set, the opener will end lifting the door merely after it starts.
A 2d problem that often occurs is that when the door opens, the cables loosen and fall off the pulleys. When the homeowner tries to close the garage door, it jambs and reverses. Often the stretch can be adjusted, but tests have shown that after springs get multiple gaps, they will continue to grow an inch or more than every 1,000 cycles. They are also more likely to break, causing impairment to hangs and pulleys. Even more extensive damage is possible if there are no safety cables on the door.
The 3rd problem with expired extension springs is that one side fatigues before the other. When this happens, ane side pulls upwards before the other, and the top section hits the pulley or mounting bolt, causing the door to stop. This is also why we discourage customers from buying simply 1 spring. The door will not open up or shut evenly, causing additional issues with article of clothing, bounden, and rollers coming out of the tracks.
The main advantage of longer life springs is that since they ordinarily last about three times longer than the standard springs, yous may never have whatsoever of these problems. If you do buy the springs, we do recommend you reinstall your safety cables or buy new ones if you don't have whatsoever. If long life springs are available in the sizes y'all need, the option will appear with part numbers catastrophe in "LL" in the listing that appears afterwards entering information in the drawdown menus.
In the early decades of door manufacturing, springs were often much larger than the standard extension springs made today. Older springs also fatigue and grow in length. Because of this, a 25" leap that has stretched five inches will measure to exist xxx" if measured while the bound is still on the door. For these reasons, and because there are no standard engineering specifications among the spring manufacturers, your new extension springs volition probable look different than your old springs. This is normal, and, bold that your new springs are for the same door height and that they have the same pull as your old ones, you tin expect them to be fully compatible.
One is that the springs lift about 10% less. On a 200 pound door that is near 20 pounds, and if the opener forcefulness is properly set, the opener will cease lifting the door just subsequently it starts.
PLEASE Note: Due to production delays, jump orders for doors higher than eight feet may be delayed 4 to six weeks. If you tin can wait that long for your springs, please annotation that in the annotate section of your order.
