Q. How much headroom is required above a commercial or industrial garage door?
A. There are different lift types for commercial, agricultural or industrial doors. When we talk about a “Standard” lift movement, here are headroom requirements based on the type of hardware:
Note: if you use a trolley-type operator, add 2 ½ inches.
IMPORTANT: Do not use a “Standard” lift movement if you have over 2’ (61 cm) of headroom. Use a “High Lift” movement. It is important to leave clear space above the garage door.
For Low Headroom applications, the minimum headroom requirement is the following:
Low Headroom Rear installation
Low Headroom Front installation
Note: if you use a Trolley type operator, add 2½ inches.
Q. How do I remove my old garage door?
A. If you are replacing your existing door with a new one, you will no doubt have to replace several parts, but they may be only screws for the hinges or worn-out rollers. You will almost certainly have to change the spring system since their size and strength are based on the weight of the door. The weight of a wood door, an aluminum door, and a steel door differ greatly.
It is important to understand that the springs used in opening and closing a garage door support the entire weight of the garage door. This means that there is extreme tension in these springs and that any sudden and uncontrolled release of these springs is dangerous and could cause serious injuries.
The first and most important step in the removal of a garage door is the release of the tension in the springs.
Removal of Extension Springs
For extension spring hardware, the tension in the springs disappears almost completely as soon as the door is completely opened.
Open the door completely and block it in this position with clamps or locking pliers firmly tightened to the track to prevent the door from closing. (See figure 1)
You can now release the cables and take off the springs without any trouble or danger.
Then, take off the clamps or the locking pliers and slowly close the door.
WARNING! Do not execute this step alone. Remember: a garage door which is not linked to a spring weighs it’s real weight and trying to handle it alone could be dangerous.
We suggest you place a wood block under the door before closing it to prevent getting your fingers caught. You can now undo the panels of your door starting by the top panel.
Removal of Torsion Springs
First of all, lock the door in the CLOSED position. You can either use the locks installed on the door or use clamps or locking pliers as shown in Figure 1.
Then block the spring shaft with locking pliers leaning against the wall (header) as shown in Figures 2 and 22. Then, insert one of the winding bars into one of the holes of the winding cone, HOLD IT FIRMLY TOWARDS THE TOP, and unscrew the set screws which are found there.
WARNING! As soon as these screws are loosened, all the tension in the spring will go to the winding bar; it is really important to keep this bar very tight to avoid a sudden release of the spring.
Let the spring slowly unwind towards you and then insert the other winding bar in the hole at the top. Take out the bottom one only when the top one is well-inserted and held firmly in your hand. Continue this procedure until there is no tension at all left in the spring. Repeat the same steps on the second spring, if need be. Release the cables and then take off the clamps or locking pliers.
You can now undo the panels of your door starting by the top one.

Q. Which is a better choice for my residential garage door: extension or torsion springs?
A. Torsion springs are located above the door and are safer and more suitable for double garage doors (14’ wide and over).
Extension springs are located above the horizontal tracks and require less clearance. They must always be equipped with safety cables because if a spring breaks, the cable stops it from falling and hurting you or damaging your car. This is all about your safety.
Q. What sort of maintenance is required for my new garage door and its accessories?
A. Rollers, hinges and other moving hardware should be lubricated with a metal lubricant.
For the tracks you can also use a metal lubricant, mainly where the tracks curve. The same goes for the springs. Apply a metal lubricant and wipe off the excess with a cloth to lengthen the lifespan of your springs.
Never put grease on the tracks. Remember that rollers must “roll” and not slide in the tracks.
Whenever you are washing your car in the driveway, go ahead and take a pass at your garage door. Use a mild liquid soap and rinse liberally. For any stubborn marks use an all-purpose detergent and avoid any abrasive cleaners.
Don’t neglect the inside of your door. Any dirt that builds up over the winter can reduce the long-term shine of your door.
If you’d like your door to keep its brand new appearance, once a year apply liquid car wax to it on a cloudy day in order to protect its luster and restore its shine.

Q. What is meant by energy efficient garage doors?
A. When applied to garage doors “energy efficient” typically means well insulated; however, even the best insulated garage door can’t prevent heated or cooled air from escaping from your home, especially if you have a finished room above the garage. If your garage door is not equipped with effective weather seals around the edges and between each section of the door, cold and heat can infiltrate your garage and eventually your home’s interior.
An important thing to keep in mind is that even if different garage doors have the same R insulation value, they are not necessarily equally energy efficient. R value does not take into account the loss of energy caused by leakage from door section joints, and other insulating factors.
