Note that I am measuring a spring that is fully relaxed because it is broken!. The length of the relaxed, unbroken spring is the specification of interest. It is harder to measure unbroken springs on an intact door because the springs should not fully unwind, even at the top-of-travel. If you can't be certain of the spring diameter from indications on the cones, then you have to go through an unwinding procedure to relax them fully for measurement, or perhaps reckon the size from measuring the somewhat smaller diameter at the nearly unwound condition when the door is at its top-of-travel (although one should not attempt to raise a door with a broken spring).
The winding technique is simply to (un)wind as far as one rod will go, where it is pressed against the top of the door, or nearly so, by the unwinding torsion. You insert the other rod in the next socket, remove the first rod, and continue. At any point you can stop and rest by leaving the active rod pressed against the door, where it will be held by the unwinding force. I would make a quarter-turn increment that way, and let go for a moment to collect my attention for the next increment, almost in a quiet, meditative alertness. While you can go from one quarter-turn and rod-swap to the next continually without letting go, working fast against the steady tension seemed to invite a kind of shakiness in my arms that was a bit unsettling. It isn't that there is much physical exertion, it is more that the tension is unrelenting, like peering over a precipice.

Winding "up" starts out easy. It finishes at the proper number of turns, by which time you are pushing against the maximum torque. Count the turns of spring winding from when the springs are slack. To be sure you're winding the right direction, all you have to remember is that proper winding makes the spring smaller in diameter and longer in length as it twists "in". On the standard door (most common), this means you push the winding bars up to wind up the spring, which is an easily remembered rule. This is very apparent and should be verified during the first few easy turns. You can also think about the correct winding direction in mechanical terms, namely which way the reaction of the spring will torque the shaft and drums, which in turn will lift the cable. This should all make perfect sense before you attempt the manipulations.
The first garage door opener remote controls were simple and consisted of a simple transmitter (the remote) and receiver which controlled the opener mechanism. The transmitter would transmit on a designated frequency; the receiver would listen for the radio signal, then open or close the garage, depending on the door position. The basic concept of this can be traced back to World War II. This type of system was used to detonate remote bombs. While novel at the time, the technology ran its course when garage door openers became popular. While the garage door remote control transmitter is low power and has limited range, its signal can be received by other, nearby, garage door openers. When two neighbors had garage door openers, then opening one garage door might open the neighbor’s garage door as well.
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.

The various increments of standard wire sizes differ by only about 0.010 inch, so calipers or a micrometer would be the tool to use to be certain of the stepped size you have, or else a trustworthy ruler marked in tenths of an inch to use the measure-10-turns-and-divide-by-10 trick. The most common wire sizes in the US are 0.207", 0.218", 0.225", 0.234", 0.243", 0.250", and 0.262".
Since 2015, we’ve tested a variety of devices such as smart locks, video doorbells, DIY home security systems, thermostats and more. We use these testing experiences to inform our evaluations of other equipment. As time and resources allow, we occasionally test new types of products, but there are still some circumstances where we’re unable to conduct in-house tests. When testing isn’t possible, we conduct thorough research using the same standards we apply to our in-house tests – this is the case with smart garage door openers. We’ve reviewed garage door openers since 2011. 

Checking if the lift drums need resetting: The old position of the lift drums on the shaft may have slipped or otherwise lost the the proper position, requiring a reset of the drum position on the torsion shaft. You will also reset the drums if you are replacing the lift cables, since the new cables will not exactly match the length of the old ones. Problems like uneven tension on the cables, or a tilted door, or a door that doesn't easily stay aligned with the tracks, can be due to an improper "set" of the drums on the shaft. So one shouldn't assume the old positions are correct. Setting the drums on a "fresh" part of the shaft will avoid the possibility of damaging the shaft from retightening in the same dimples.


Garage door manufacturers typically produce garage doors fitted with torsion springs that provide a minimum of 10,000 to 15,000 cycles and are guaranteed for three to seven years. One cycle is a single opening and closing sequence. Most manufacturers offer a 30,000 cycle spring. However, it is important to remember that if the weight of the garage door is increased by adding glass, additional insulation, or even several coats of paint, the life of the torsion spring may be greatly reduced. Additionally, springs at highly humid environments, such as coastal regions tend to have a significantly shorter cycle life, due to the corrosive cracking.
To estimate the maximum physical force required to wind these springs, consider that they are balancing the weight of the door with a torque applied to a lift drum on each end of the torsion shaft. The lift drums have a 2-inch radius, which is the standard residential size, and corresponds conveniently to about a 1-foot circumference. If we pessimistically assume the 10-by-7-foot door has a weight of 350 pounds, this implies a torque of 350 pounds on a 2-inch radius, that is, 700 inch-pounds, or 58 foot-pounds. Each of the two springs should be exerting slightly less than half of the balancing torque, or 29 foot-pounds. Compare this to, say, the bolts in an automobile, which are typically torqued to values of about 50 foot-pounds, or tire lug nuts, which may be torqued to well over 100 foot-pounds.

While you can certainly redo any security features on your garage door, it is often wise to replace the entire door if in fact that is the way a burglar gained access to your house. A new security code may seem like enough, but you don’t know how the thief figured out the old code in the first place. If the motor was disengaged, the issue might be a design flaw in the door itself. The best way to ensure that the thief doesn’t return or another thief doesn’t take advantage of the same unknown security weakness is to install a new door. Again, doing so with give you access to the kinds of robust security features that are being installed and implemented in the newest garage doors on the market.
Screw - Screw-driven lift systems attach a long screw to the motor to move the garage door. These systems are powerful, fast, relatively quiet and require less maintenance than typical chain- or belt-driven systems. Genie and Overhead Door are two popular brands that make screw-driven systems. Based on our research of Genie’s line, you can expect to pay $244 on average for a screw-driven garage door opener.

Most wood doors are sectional roll-up doors, though a swing-up wood door that’s meant to be painted can be affordably built in the driveway from a wood framework and plywood. Custom wood doors are typically made of durable softwoods such as Douglas fir, cedar, redwood or cypress, or from hardwoods such as oak or mahogany. Appearance-grade hardwoods are relatively expensive.

If you have paired springs, you can take a shortcut here instead of using locking pliers. Simply apply a slight torsion to the bar by clamping one of the springs with an easy half-turn or so applied. This will hold the lift cables in slight tension while you wind the other spring. If you have a single spring design, you can't use this trick, and have to use the locking pliers.
The Entire job from order through installation was great. The person at Home Depot who helped us made sure we knew exactly what was needed and went over options answering all questions my Fiance had before I could.

Speed of a falling door:: Physics tells us that the transit time of a free-falling body is sqrt(2x/g), where x is the length of the fall and g is the acceleration due to gravity (32.2 ft/sec^2). If this typical 150 lb door were to fall an equivalent of 3.75 feet, this falling time would be sqrt(2*3.75/32.2) = 0.48 seconds (480 milliseconds). The terminal velocity is gt, or 0.48 seconds * 32.2 ft/sec^2 = 15.5 ft/sec = 10.6 mph.
Loosening or tightening the set-screws is the moment of most risk, since the end-wrench is a potential missile if you slip, and your hand is close to the cone. When the wrench is removed and only the rods are in place, it would seem that the worst that could happen is that the rod is flung out and the captive spring and cone rattle around, assuming you are keeping yourself clear of the rod's radial disk of rotation, and not leaning on the rod such as to fall into the apparatus were the rod to slip out of your grasp. The torsion shaft design has the virtue of capturing the mass of the spring and cones reliably on the shaft, preventing these parts from launching themselves as projectiles, even in an accident.
