The wire size and winding direction are easily discovered and proved, as I will explain below. You absolutely must know and understand the critical measurements of your old springs to order replacements. This assumes that the old springs were the correct to begin with; it is not uncommon to have incorrectly sized springs on a door due to a previous sloppy installation, or a significant change in weight of the door.


If you are replacing an old garage door, the first step is to measure your garage opening to ensure you are choosing a door with the correct dimensions. Even if you feel confident that your door is a standard size, measuring first can help ensure that buying your door is an enjoyable and smooth process. View our installation guide to get the needed measurements for your door. If you find that you have an odd-sized garage door, use our QuickDraw tool to see how a specific model will look in your desired size. If you have a unique vision for your home's curb appeal, Clopay can also design custom garage doors to meet your specifications.

Once the springs are relaxed and loose on the torsion shaft, the lift drums lose their tension on the lift cable, and the cable comes loose. The end of the cable is terminated by a press sleeve, which locks into a ramp on the drum. Different drum styles have a bolt or other method to fix the cable end to the drum. These steel cables are springy and won't stay in place without tension. If my pre-inspection had showed that these cables were worn or frayed, then I would have ordered proper replacements ahead of time from the spring distributor, since this is the opportunity to replace them. Standard hardware-store cable and fittings are not appropriate.
Since we're using an 18-inch (1.5 feet) winding lever to wind each spring up to 29 foot-pounds, we must apply a maximum tangential force to the end of the winding lever of about 20 pounds. Later we'll see that the actual weight of this rather dense door is 238 pounds, implying a maximum tangential force on the winding levers of only about 13 pounds!

Cable fail-safe redundancy: Based on the proper setting of the drums on the torsion shaft, the two lift cables divide the lifting force equally to keep the door level as it rises. This not only levels the door, but also provides a fail-safe mechanism. If one of the cables should fail, such as from breaking or losing its end attachment, the other cable will then carry the full weight of the door. This will pull the door up on one side with twice the normal force, while the other side falls from its now unsupported weight, tending to make the door bind in its tracks and jam. Although not foolproof, this is a safety feature of the design which keeps the door from falling catastrophically if a cable were to fail while the door was traveling. The jammed condition also prevents a lowered door from opening with the hazard of a single broken cable, further minimizing the chances of both cables failing. Since if one cable fails the other must sustain the full weight of the door, the cables and attachments are rated many times the normal working load of half the door weight. A proper safety inspection of the door should include a critical look at the cables and their attachments.

At this point I weighed the unlifted door to confirm and fine-tune my calculations. This is not strictly necessary, but it makes the adjustments easier to perform, if you happen to have a scale with the requisite capacity. With some helpers, we first lifted the door a few inches and rested it on blocks of wood to provide clearance underneath. Then I slid a 400-pound-capacity freight scale under the center of the door, we lifted again to remove the blocks, and lowered the door gently onto the scale. This door weighed in at 238 pounds, which is very heavy for a single-car door. Since the outside of the door carries the 3/4-inch plywood paneling to match the house, and that plywood weighs about 2 lbs/sq-ft, I estimate the door weight to be about 7 x 10 x 2 = 140 lbs of paneling with the rest 238 - 140 = 98 lbs the interior panels, hardware, and cobwebs. Knowing this total weight will help later in adjusting the torsion on the springs. After weighing, we removed the scale and blocks, leaving the door fully lowered again. Had I not had a high-capacity freight scale, I might have improvised a crude weighing device from levers and smaller weights of known mass, or a lever arm pressing a reduced proportion of the full weight onto a lower-capacity scale. Another factor to remember is that The weight of a wood door can vary with humidity.
I obtained my parts, as described on this page, from American Garage Door Supply Inc. (http://www.americandoorsupply.com/) They may have raised their small-order prices or imposed a minimum order since I ordered from them in 2002 at the prices in my essay above. The Web site offers a free catalog by PDF download or mail. Springs in 2005 were priced at $2.25/lb.
