Dodging a falling door:: Reversing this equation gives us x=gt^2/2 as the fallen distance x for a given time t. How much time would you have to dodge a falling door if the spring were to suddenly break at the top of travel? Let us assume you are 5.5 feet tall, so the door will hit your head after falling 2 feet from its 7.5 foot fully-raised height. This 2-foot fall takes sqrt(2*2/32.2) = 0.35 seconds (350 milliseconds). The quickest human response time is about 200 milliseconds, so even if you are alert to the hazard, this leaves you only about 150 milliseconds to accelerate and move your noggin out of the way. If you are an Olympic gold medalist in the 100 meter dash, you can accelerate (horizontally) about 10 feet/second^2, and your 150 milliseconds of wide-eyed panic will move you all of 10*0.15^2/2 = 0.11 foot = 1.35 inch.
The open-ended work-order trick: You may be very surprised if you allow work to proceed without signing a work order with a specified price. Or, you may sign a work order, and think you're protected against open-ended wallet-reaching, only to find a much higher price due at the finish than you expected, because you signed a "parts as needed" order that got loaded up with a long list of parts (that likely were still in serviceable condition). You might have been quoted a price, but then get a bill for that price plus a lot more added for the "service call" and the "parts", and be told the quote was just for the labor. While this is the normal way of abusing your finances down at the hospital, you shouldn't agree to it for a garage door service call. These guys are not doctors.

You might be thinking: Aha! Why don't we lift the door, clamp it in place, and install the springs while they are thus safely unwound, rather than deal with all that accumulation of hazardous torque? The answer: At the top-of-travel, the unwound springs are not fully relaxed; they are still clamped to the torsion shaft with a significant stretch along the shaft axis, plus about a half-turn to keep the door snug at the top. This extra length amounts to the stacking of extra turns that accumulate from winding, also termed "spring growth" in the business. In my case this is about 7 turns of 0.2253 wire, or about 2 inches. Stretching the spring that much and clamping it with a half-turn or so of twist is not feasible.

Spring rate and torque: In my spring replacement above, the wire size was d = 0.2253 inches, and the ID was 2 inches, giving a mean diameter D = 2.2253 inches. The number of coils is L/d = 24 inches / 0.2253 = 107, less about 5 dead coils on the winding cones, or 102 active coils. Thus the spring rate is K = (π*28.5*10^6 * (0.2253)^4) / (32 * 102 * 2.2253) = 31.8 in-lb/turn (IPPT). Winding 7.5 turns * 31.8 in-lb/turn yields a torque of 238 in-lbs per spring.
With good looks, modest cost, and solid return on your investment, a new garage door is the Triple Crown of curb appeal projects.

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.
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.

The not-so-competitive advertising trick: How about this racket: We have all heard how you should get at least three bids for any home improvement jobs, right? In some areas the largest ads in the yellow pages are from a single business using various names and phone numbers, masquerading as independent competitors. When you call asking for prices, "they" all quote you very high numbers. You are tricked into thinking you have shopped around for the prevailing price. (The more modern version of this is multiple Web sites that all direct you to call the same person.) If you've ever had to call a plumber you may have unknowingly been a victim of a similar trick.
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.
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.

The disaster-is-nigh technique: As he inspects your door, the serviceman grimly calls your attention to "cracks" in your garage door. These appear very faintly in the middle of the door where the panels bow under their own weight when the door is up. This is normal, but the type of thing you wouldn't casually observe yourself. This surprising revelation disarms you, and you may find yourself strangely susceptible to the pitch for an entire new door.
Smart garage door openers aren't as expensive or hard to find as you might think. In fact, no matter what smart home platform you're using, there is an opener that will work for you. Smart garage door controllers add convenience like remote access, voice control, scheduling and vehicle detection to your garage door. You'll never need to wonder if you left it open ever again.
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.
Because your garage door can be customized, pricing varies. Our Clopay configurator will help you review pricing as you begin your project. You’ll start with your door size and whether you need a single or double car door. Next, you can choose the collection of door, which gives you options of various materials and styles. Then, you’ll choose your construction, which allows you to decide what you need in terms of energy efficiency, durability and noise control. Lastly, you will be able to visualize the design and see an end price. Other optional add-ons include windows, decorative hardware, smart features and the r-value. However, you do not have to use the configurator. We also install standard garage doors that have not been customized so you know the product price early on in the process.
