Spring index lower limit: DASMA standard 102-2004 provides a lower limit of 6 for the spring index, which is symbol C in our formulas above (section 9.3). Other interesting items in this standard include an upper limit for how much the door sags when raised (no more than 1/120 of its width, section 9.2.1), that each of the two bottom brackets should sustain twice the door assembly's weight (section 9.2.2) for a total safety factor of about 4, and that the lift cables should provide a safety factor of 5.
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.

Safe automatic door openers. All automatic openers must now have an auto-reversing mechanism and photoelectric eyes located near the floor on both sides of the door (see photo). If the door is closing and the beam between the eyes is interrupted, the door will automatically reverse. If the eyes aren’t connected, the door won’t operate.

Horsepower: The horsepower measurement, often shortened to HP, describes the power the garage door opener motor has. A motor with a greater horsepower measurement will open and close the door more quickly, while also being able to handle larger and heavier doors. Motors between 1/2 HP and 1 HP are the most common for residential garages, FeldCo says.

Garage remotes work by sending a coded signal via radio frequency to the garage door opener. If this code matches that of the opener, then the motor will operate and raise or lower the door. Older devices use a single coded switch, whereas newer systems utilise a rolling code that changes each time the remote is used, increasing the security of the door by offering billions of combinations.
Door styles - in addition to the styles just mentioned, it is important to also consider additional features such as windows across the top of the door to provide light inside of the garage, the use of steel or wood frames to give decorative doors added security and stability, and insulation which can reduce energy costs in the attached garage by an impressive 15 to 20%; and
Here is what a winding cone looks like without the spring. The threads that grip the inside of the spring coils are ambidextrous, so you can use the same part on either right- or left-hand-wound springs. The cone size is specific for a certain inner diameter of springs, so if you have the wrong size, the cone will slip inside the spring (cone too small), or not fit (cone too big).

However, in addition to potentially causing injuries to the under-prepared DIYer, a malfunctioning door can become a safety hazard to you and your family. Keep in mind, according to the National Electronic Injury Surveillance System (NEISS), over 13000 people checked into hospitals with garage related injuries in the United States in 2007. You don’t want to turn a loved one into a statistic just to save a few dollars!


One might stack lumber or arrange some other low platform for a steady footing, instead of the ladder. The aluminum ladder shown here is the splendid 16-foot Krause Multimatic, which carries a Type 1A Industrial rating (300 pound working load); I highly recommend it. However, product liability apparently forced this company into bankruptcy in September 2000 and the company ceased operations in June 2001; see http://www.krauseladders.com (this Web site went dead sometime in mid-2002). The world is a dangerous place.

There are plenty of garage door accessories to make your garage safer. Sears carries replacement safety sensors that will detect anything in the way and keep it from shutting. If you have a small garage or it's full of gardening equipment, a laser parking assistant will help you find the perfect spot every time. You can set it so it hits the perfect spot on your dash as you pull in. You'll also be able to find new tracks to replace worn opener tracks.

Those who benefit from this anti-competitive behavior have many excuses for it. They claim that the product is too dangerous and infrequently needed for the public to purchase directly. They say the job is hazardous and requires techniques and tools with which the amateur will rarely practice, which is true. They write me in anger saying I don't understand how expensive it is to put a truck on the road with a technician and parts and salary and benefits and insurance and advertising and every other common business expense. They say it will take the homeowner hours of effort to do this safely and correctly, while they can do it in a fraction of that time and at a price that isn't worth the effort to save. But should they set themselves up as the judge of what you can and cannot do? Of what is an economical use of your time? Imposing minimum order quantities or charging retail prices for small orders is legitimate; inquiring into the purchaser's background is not.
Today's garage doors come with those door sensors, and if anything is in the path of the door the sensor detects it and raises the door back to the open position. These precautions are important for families with young children or pets. Even if you don't have a mini me or furry friend running around your yard, it's a good idea to have a garage door that is safe for you, your guests and your belongings. 
Repair of garage doors is a licensed trade in many jurisdictions, and manipulation of the market inevitably follows. Look in your phone book yellow-pages under "garage doors" and you'll find a lot of big, costly ads for door service. The profits are quite juicy, I'm sure. The customers need service urgently, and this need will typically arrive suddenly and at a busy time when shopping for prices is not convenient. A few dollars in parts, an hour of labor and travel, and a $150 invoice (assuming the outfit is charging fairly, some are not). Lately (2006) I hear of outfits charging $200 or $300 for this work, and occasionally a story of a $500 or $800 service call. You'll also find the phonebook advertisers waiting eagerly for your call, because artificially high prices inevitably lead to an oversupply of service firms working under capacity.

While winding or unwinding, one must be mindful of the possibility that the spring could break during winding process itself. If that should happen while the spring is significantly torqued, hazardous forces on the winding bar will suddenly become unbalanced, and the bar will take an unexpected jump, possibly injuring your hand or anything else in its path. At the same time, the spring remnants, although captured on the torsion bar, will create a frightening racket that would give the bravest soul a start. So your winding technique should be firmly in control of the rods, and you should not be so delicately perched on a ladder such that a startle will result in a fall.
End treatments: Torsion springs also are made in a variety of end treatments. The "standard torsion end" is most common, as is pictured in my examples, consisting simply of a short, straight length of wire projecting tangentially. Various non-standard end treatments have longer "ears", U-turns, ends bent in toward the center or along the axis, or even loops. Non-standard ends are used in end fasteners peculiar to various manufacturers, which would seem to serve mostly as a guarantee that you buy overpriced replacements from that one source.

The technician that came out, Todd Noel, was very friendly and professional. He fixed my problem quickly and did not overcharge me for something that I did not need. He also made some great recommendations for future work. Because of his level of service and my customer experience, I highly recommend Precision and will use them again in the future.

Locating a contractor - there are many professional overhead garage door companies. It is always advisable to contact at least three different agencies and request a bid or quote for the work. Be sure that each quote includes the costs for a few different types of doors, any installation fees, and the cost of wiring the electronic openers. Standard prices range from:

Recently another type of opener, known as the jackshaft opener, has become more popular. This style of opener was used frequently on commercial doors but in recent years has been adapted for residential use. This style of opener consists of a motor that attaches to the side of the torsion rod and moves the door up and down by simply spinning the rod. These openers need a few extra components to function safely for residential use. These include a cable tension monitor, to detect when a cable is broken, and a separate locking mechanism to lock the door when it is fully closed. These have the advantage that they free up ceiling space that an ordinary opener and rail would occupy. These also have the disadvantage that the door must have a torsion rod to attach the motor to.


Not only was the upward-lifting garage door and the electric garage door opener invented by Overhead Door Corporation’s founder C.G Johnson in the 1920s, but we also have a tradition in excellence for garage door repair, service and maintenance.

In this article, we’ll tell you the difference between a safe door and one that’s unsafe. We’ll also give you the helpful tips you’re not likely to find in the manufacturer’s instructions to correctly, and safely, install a new door with a torsion spring and do-it-yourself tensioning. Installing a new, double garage door yourself will save you several hundred dollars and should take eight to 12 hours if you’re fairly handy. You can do most of the project yourself, but you should recruit help for removing the old door.

Most electric garage door openers have two lights: one in front of the opener and one behind or sometimes they sit side by side. They should provide enough light for you to get into your home from your car. Generally, people don’t leave the garage light on when it’s not in use, so it’s nice to have a temporary light when you arrive home. The length of time the light stays on varies according to how it is programmed. In most instances, you don’t need more than a few minutes from the time you leave the car to when you enter your home.

The low rating on the CS is due to the fact that inwas out of town and my wife called because the garage door wouldn't open. We had repairs to the only other exit, and the CS said because it could be opened manually, it was no emergency. She was stuck in the house for over Sixteen hours. No emergency crew came out. Steve, a tech who came out the first time, fixed the door. It is not his fault CS took their sweet time to help a 45 year customer. I commend Steve. I do NOT have anything good to say about CS.
Install the stiffening strut on top of the top section of steel doors with the section lying flat. Then install the opener bracket that replaces the center bracket between the top two sections. While you’re working on the sections, protect them from scratches by putting carpet scraps on top of your sawhorses. Now, slide the rollers into the roller brackets.
