How many times a day do you open or close your garage door? You probably don’t even know because we take our garage door for granted until…. Until it doesn’t go up… until it doesn’t come down… until it gets noisy, difficult to open by hand or some other problem develops. You need help – and if you’re locked in or locked out, you need help in a hurry. You need A-Authentic Garage Doors. Here’s why:
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.
Reduce your monthly energy bill with insulated garage doors. They feature an insulated core made of polystyrene that’s surrounded by a steel cover. This can help you maintain the temperature inside your home no matter if it’s extremely hot or cold outdoors. Insulated garage doors are also known for their quiet operation. Be sure to look at the insulation rating – or R-value – when considering garage doors. The higher the R-value, the better the insulation.

Garage door openers manufactured and installed in the United States since 1982 are required to provide a quick-release mechanism on the trolley that allows for the garage door to be disconnected from the garage door opener in the event of entrapment.  Garage door openers manufactured since 1982 are also required to reverse the garage door if it strikes a solid object.
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

Spring rate, torque, and lift: The spring rate K for these measurements is π*28.5*10^6 * (0.273)^4 / (32 * 140 * 1.72) = 64.5 IPPT. Applying 7.5 turns on this rate will yield a torque of 7.5 * 64.5 = 484 in-lb, which on the 4-inch drums (2-inch radius) yields a lift of (484 in*lbs)/(2 in) = 242 lbs. Again we find good agreement with the approximate door weight of 238 lbs.
It can be very problematic if one's car doors are not fitted properly. The garage is the place where people house their cars with a lot of safety and security and it is only natural that they would want the very best for their doors. With the increase in burglary and other anti-social activities, it has become all the more important to take the necessary step towards building a strong garage with reliable door opener. At Larry Garage Door, we try to do this with the most efficient staff who are dedicated towards serving their clients and give them a door at an accessible price. We have made sure that whichever type of garage our client might have, they will find the right door and opener with us. We have years of experience with us and we have worked with clients all over the California's Central Valley. We only use the best aluminum and steel if their preference is more towards the metal doors, and also giving a very low price to our clients.
Containment cables. When old extension springs break, the springs and cables become heavy whips that damage cars and even injure people. To solve the whipping problem, manufacturers now offer containment cables that run through the center of side-mounted extension springs. If you have extension springs and don’t plan to replace your door, make sure the springs have these containment cables, or have a professional install them.
The technician, Robert Helton, was very pleasant, helpful, and professional. He repaired the garage door opener expeditiously and explained why it hadn't worked properly. He also checked the chain mechanism and the door itself and showed me how to manually work the door should I need to do that in the future. I was very pleased with this repair work.
We love the fact that you can connect the Chamberlain Whisper Drive with a phone app for long-distance control, as well as the fact that the door will secure itself if you forget to do so. As with any technology, there is a learning curve in which the kinks will need to be worked out. But overall, very few owners have anything bad to say about the Whisper Drive. One smartphone user expressed his satisfaction with the product by saying, “I can check if I've left the garage door open and close it from my office!”
Trading diameter for length: Observe that in the spring rate formula in the table above, factors D (diameter of coils) and N (number of coils) appear together in the denominator of the spring rate formula. Algebraically, given equal wire sizes, this means that the product of the coil diameter and overall length produces the spring torque, not the diameter or length alone. Physically, this means that you can trade off torsion spring coil diameter versus overall length in inverse proportions to maintain the same torque rate. Trade-off example: A spring with 2-inch diameter coils that is 36 inches long equals a 1.5-inch diameter spring that is 48 inches long, because the product in both cases is 72 (inches squared). This assumes that wire size is equal in the trade-off, and that you have not counted dead coils in the length. Service technicians use this principle to make quick substitutions for what's on their truck versus what you need. But if you understand this, you're ahead of many technicians who don't know this trick. Maybe now you can educate the next one you hire.
