Manufacturers and distributors of torsion springs believe they are better off not retailing their product directly to the public. They believe they are maintaining higher prices for their product by restricting sales "to the trade." One brochure for parts even flatly stated, "We do not sell to the end user. We protect our dealers," which would seem to be prima facie evidence of an illegal restraint-of-trade scheme. But this is an old story which is true of virtually every product and service, going back to medieval guilds and before.

When you're done watching this video you'll know how to determine whether the company you hired to replace your garage door spring installed the right size spring on your door. You'll also learn the consequences to your garage door opener if the wrong size spring is used. If you are having a problem with your garage door spring, the 2:30 minutes you spend watching this video is time will spent.
A standard residential door raises 7.5 feet, but since the door goes horizontal this is equivalent to raising the whole door for half that distance, or about 3.75 feet. So if the door weighs, say, 150 lbs, then the energy supplied by the springs is 3.75 * 150, or about 563 foot-pounds. This is like throwing a 50-lb sack of cement up a 11-foot flight of stairs. Or catching a 50-lb sack of cement dropped from 11 feet up.
Torsion springs are devices that lift most of the weight of a garage door so that the door can be opened manually or by an electric opener. The torsion principle is applied via an efficient and economical apparatus consisting of a torsion shaft under spring torsion, which turns lift drums, which wind cables attached to the door near the bottom. All of this apparatus is mounted over the top of the door. The energy stored is sufficient, in an uncontrolled release, to break things, hurt you, or perhaps even kill you. The same could be said of jacking up your car to change a tire, or mowing your lawn, or raising children, so it is not crazy to want to do this yourself.
Finally, one of the most important garage door innovations over the years in increased child safety features. Sensors can detect when a child or pet is crossing the threshold while the door is closing, prompting it to stop immediately. Furthermore, doors can also sense when something is being pressed by the door, causing it to stop before inflicting a brutal crushing injury.
Overhead Door® openers and garage doors are built with longevity in-mind. By performing a few routine tasks, you can help ensure your garage door system stays safe and stands the test of time. One important part of garage door system routine maintenance is to make sure the photo-eyes have not gone out of alignment. The photo-eyes are the infrared sensors which monitor whether the space at the bottom of your garage door is clear. When these sensors are not lined up properly they will keep your door from closing. Make sure to occasionally check your photo-eyes’ alignment to ensure they are correctly detecting obstructions to keep your garage door safe and operating properly.

Roller doors ("Sheet Doors"-USA) are usually constructed of corrugated steel. They evolved from cover window and door coverings. Other materials can be used (e.g.; transparent corrugated fibreglass) where strong impact resistance is not required. Corrugations give the door strength against impacts. A typical single car garage roller door has a preloaded spring inside the rolling mechanism. The spring reduces the effort required to open the door. Larger roller doors in commercial premises are not sprung (except USA) and use a manual pulley and chain system or a geared motor to raise and lower (roll up and roll down) the door. Roller doors cannot be effectively insulated.

Called for an appointment and was surprised that I could have a tech come the same day. Matt arrived ahead of schedule, inspected the garage door and gave me a tune up to get things working properly again. He explained what would need to be done in the future, and the cost. I will certainly call them when the time comes to get that work done.read more
I mentioned earlier that this apparatus had at least one prior spring replacement, with a single longer spring having been replaced by two shorter springs. The clamping of the original spring had pressed dimples and an eccentric distortion into the hollow shaft. While this distortion was large enough to block the old cones from sliding across, I was able to remove the old hardware by just sliding them in the other direction. I did not have to bother trying to press out this distortion, since I could just work around it.
While a sudden issue is usually easily repaired, a consistent issue that has gone unaddressed for months or years will likely require a total replacement. The problem is that garage doors have a number of heavy, powerful moving parts. If the door is working as it is designed, it can open and close hundreds and hundreds of times without issues. However, if there is even a small issue in the lifting mechanism that repeatedly influences the movement of the door, you will soon find that the damage caused over those hundreds of lifts can’t be fixed.
The torsion shaft with lift drums on the ends is above the door. The standard residential door shaft is a 1-inch outside diameter hollow steel tube. The inside diameters of the bearings, drums, and winding cones are sized to loosely fit that 1-inch diameter shaft. At the center is a bearing plate, on either side of which are the torsion springs, or in some cases just one larger spring. The spring pictured on the left in the photo is broken about 1/4 of the way in from its left end. The black shaft with dangling rope and door bracket is the track for the electric opener.

When picking the best garage door for you, a good place to start is with material type. Most garage doors are made from either wood, steel or fiberglass. These three materials are strong, durable and each have their unique benefits at various price points. In order to pick the perfect fit for your home we have developed the DoorView® garage door designer. This interactive visualizer tool helps you design your dream door and allows you to see how it will look on your home with just the push of a button. You can also try it on your Apple iPad and Android devices.
Two of the spring references specifically for the garage-door industry are the APCO Spring Manual by Bill Eichenberger, and the Torsion Spring Rate Book by Clarence Veigel; these give tables of spring sizes and torque constants. Spring engineering principles in general are described in the Handbook of Spring Design published by the Spring Manufacturer's Institute; the formulas allow you to calculate torque constants knowing only the geometry and the Young's modulus of the material. You can also find some brief spring information in standard references like Machinery's Handbook and Marks' Standard Handbook for Mechanical Engineers.
The standard winding tools are simply a pair of 18-inch lengths of mild steel rod, 1/2-inch diameter. Winding cones can have different socket sizes (such as 5/8 inch instead of 1/2 inch), so it is important to measure the socket and select a matching rod diameter. Also beware that poor-quality cones may have a sloppy fit to the winding bars, and a loose fit presents a severe hazard of slipping at the worst moment; anything more than about an inch or two of play at the handle end is too loose for safety. I bought a 3-foot length of zinc-plated 1/2-inch diameter steel rod from Home Depot for about $3, which conveniently cuts into two halves of just the right length (the store might even cut it for you if you ask). A steel supplier selling at commodity prices might charge about 50 cents or so for such a piece that weighs about 2 lbs. Drill rod would work if used in the annealed condition in which it is originally sold, but the added expense provides no benefit and the brittleness (if it had been hardened and not annealed) would worry me a bit. Rebar, threaded rod, screwdrivers, etc., are absolutely foolish as they will not fit the socket snugly. Aluminum rod is definitely too weak, and will bend under the torque that must be applied. Longer rods would make for more leverage but unwieldly swing; shorter rods make for uncontrollable swing. As we'll calculate below, the 18-inch standard tool length is an appropriate compromise. Note that you do not need 18 inches of ceiling clearance above the torsion shaft to use an 18-inch rod, since you need not swing the rods above horizontal when winding.
Stress and lifetime: Calculating the maximal stress in the wire is useful for estimating the lifetime. Using the formula above, the bending stress S in the spring wire is 32*238/(π*0.2253^3) = 212 Kpsi. The spring index C is D/d = 2.23 / 0.225 = 9.88. The Wahl correction factor is Kw = (4C-1)/(4C-4) + 0.615/C = 1.15. The Wahl-corrected stress is Kw * S = 1.15 * 212 Kpsi = 244 Kpsi. This predicts about a 10,000-cycle lifetime, which is the standard "cheap spring" configuration originally installed. Note that while this stress is proportional to the torque being applied, it is also in proportion to the inverse third-power of the wire size. Thus slightly heavier wire sizes (and suitably adjusted D and/or L) radically improve the expected cycle lifetime of the spring.
Weight and cost: The 24-inch-long spring has a calculated weight of 8.4 lbs, not counting the winding cones. At less than $1/lb wholesale, and $3/lb retail for fabricated steel products, this spring should sell for about $8 to $25 (2005 prices) each, depending on the market and source. Since a pair is required, the expected cost for a pair is $16 to $50.
Fortunately, owners aren't bashful about weighing in on their garage door openers. Though some models get only a handful of reviews others receive hundreds of unique ratings on sites such as Amazon, Home Depot and Lowe's. If you are interested in a Craftsman garage door opener, Sears is the place to visit. While our research reveals that no garage door opener is perfect, several models jump to the fore as offering good performance and good value in the eyes of owners. These are the openers that we've named Best Reviewed for this edition of our report.
Lower the door and dismantle it by removing the hardware. Lower a double door by recruiting at least two helpers to help with the weight, and place a 2×4 block under the door to prevent smashing a foot or finger when it’s lowered. Remove the sections one at a time by disconnecting the rollers and brackets. If you have windows, tape them to help control flying shards if they break. Then remove the old roller tracks and remaining hardware.
The most common grade of torsion springs have an expected life of about 10,000 cycles. The hardened and tempered steel experiences tremendous forces each time the door opens or closes. Gradually, the steel fatigues with each flexure, and eventually cracks and breaks, usually releasing its stored energy in an instant with a horrific "sproing" noise or bang. If you average about two car trips per day, opening and closing the door a total of 4 times daily when you come and go, then that expected life becomes 2500 days, or only about 7 years. If you have an automatic opener, then if you're like me, you tend to cycle the door even more frequently, and can expect the need for spring replacement even sooner. Moreover, my three-car garage has three doors, so on average I can expect a repair job every few years. Over a lifetime, it is very economical to do these repairs myself.
By watching the chalk mark while winding, you can count the number of turns applied, and confirm the number later. My standard-size door (7 foot height) with 4-inch drums has a nominal wind of 7-1/4 or 7-1/2 turns, which leaves 1/4 or 1/2 turn at the top-of-travel to keep the lift cables under tension. After 7 turns on the first spring, I clamped down the set-screws, weighed the door again, and found a lift of about 100 pounds in reduced weight. As expected, this wasn't quite half of the full 238 pounds, nor would it leave any torsion at the top-of-travel, so I added an 8th turn. The door now weighed 122 pounds on one spring, which was ideal. After winding the other spring, the door lifted easily, with only a few pounds apparent weight. This confirmed that the spring choice was properly matched to the door design. I engaged the electric opener trolley, and adjusted the opener forces down to a safer level suitable for the new, improved balance. The door was now ready for return to service.
