Right-hand versus left-hand winding: Springs are chiral, that is, wound or "laid" in either a left- or right-hand orientation. This is a critical property of their design and specification; you cannot substitute a left for a right or vice versa. If you were to grasp the spring in your hand, and if your right hand orients the tips of your fingers like the ends of the coiled wire when your thumb points "out" of the core of the spring, then you have a right-hand spring; likewise left (which end you grasp does not matter). (This also happens to match the "right hand rule" of magnetic polarity, if you happen to be knowledgeable in such esoteric subjects.) Another way to identify the winding is to examine the spring vertically in front of you; if the coils facing you rise going to the right, it is right-hand (thus you can remember, "rise to the right is right-hand"), and likewise left indicates left-hand. Another way is to view the coil axially; a right-hand spring winds in a clockwise direction as it recedes away, and a left-hand spring counter-clockwise. Yet another way, not so easy to remember, is to hold the spring vertically and compare the coil shape to the letter "Z" (indicates right-hand lay) or the letter "S" (indicates left-hand lay).

The belt-driven Chamberlain B970 garage door opener is powerful and well-featured. With a 1.25 HPS motor, it's got all of the strength needed for just about any residential garage door, and the motor and belt are covered by a lifetime warranty. The feature line-up includes built-in Internet connectivity for those who want to be able to monitor and operate their opener from afar, and a battery back up in the case of a power outage.


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. For instructions on how to install a new garage door opener, see How to Install a Garage Door Opener.

Repair Sagging Garage Doors – As doors and homes age, they can shift and move and sometimes this results in a garage door that needs to be realigned or reinforced. We will send a technician to your home to adjust the doors and to inspect the entire opening to make sure the door isn’t damaged. Once we understand the problem, we will fix the needed parts and make any adjustments to the door.


The usually recommended rule for a door being properly balanced is that it should lift "easily" through all its travel. The door may also remain stationary if let go somewhere around the middle of the travel, but a smoothly rolling door many not show this behavior (while a sticky track will!), so easy travel is the only reliable test for proper balance. A difficult door may be due to stiff bearings or rollers in the mechanism, tracks out of alignment, etc., not necessarily the torsion spring adjustment.
An enantiomorphic (mirrored) pair of springs, such as my standard door uses, will consist of one left-hand and one right-hand spring. Note that this "right" and "left" has nothing necessarily to do with whether the spring is mounted on the left or right of the center bearing plate. Indeed, with my standard door, if you stand inside the garage, facing out, then the spring to the left is a right-hand-wound spring, and the spring to the right is a left-hand-wound spring. The photos above and below of the broken spring show that it is a right-hand-wound spring.

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.
Single panel doors are constructed from one monolithic panel. From the closed position a single panel door swings up and overhead with a hinge on each side (known as jamb type hardware) to the fully open position. A disadvantage of monolithic panel doors is that the swing up arc of the door occurs partially outside the garage. This means a vehicle must stop and park several feet in front of the door to avoid being hit by the garage door when it is opened.
When I called to schedule the repair service, I was transferrd 5 times and spoke with 6 service reps. Each rep was very confused by my request to get my garage door repaired. One rep actually told me that Sears doesn't repair garage doors. I had to tell her that Sears installed the door. When I finally found a rep who could schedule my service, it took one week for the appointment.
You might genuinely need some extra parts when you thought you simply needed a broken spring replaced, and a good serviceman will perform a simple inspection to identify such parts. Nor is it unreasonable for a business to charge separately for a service call versus repair work actually performed. But the best protection for you as a buyer, being somewhat at the mercy of whomever you decide to bring on site, is to understand what is being done, and ask intelligently for a clear explanation or demonstration of why extra parts are required.
