Garage Door Installation Instructions

The installation instructions for the garage door outlined here are only general and are not a full set of instructions. For absolute complete instructions, you can review your installation manual. But it’s not as hard as some would assume to mount a garage door. It needs being able to take reasonable steps to get them in order. Measurements are the first order of business.

Before you can get started, you’ll need to have some precise measurements. They will help decide what door size you need and should be written down so that they will not be missed. Have the height and width of the door opening taken first. This will give you the starting point for your figures, which will again represent the size of your door.
The next move is to find out a side-room. This is the area on the same side, from the side of your door to the garage wall. For your regular extension spring and torsion spring, the vertical track would enable you to have at least 3-3/4 on your side. Then you’ll need to have 5-1/2 for the spring extension.
Your next measurement is for your ‘head-room’ to be worked out. This will be the amount of space up to the ceiling starting at the top of the door. In this case, you’re going to need 10 and 12 for the torsion spring for an extension spring. If you get into a situation where you have little headroom, then just for that occasion, there is special hardware made. If you intend to install a garage door opener, you’ll need more headroom.
Now it is time to get the ‘back-room’ numbers. This would be the gap from the opening of the garage door all the way to the back of the garage wall. This should add up, plus another eighteen inches, to whatever the height of your door is. And as above if you intend to put the door opener in the garage, then you’re going to need more space.
You will now have the door opening ready for installation by having your measurements taken and written down. You should have a framework of 2×6 wood jambs on the inside of the door opening. This wood is expected to match the headroom height you measured just a bit ago. They must be level and plumb, and if old, the wood should be replaced by new. Make sure if there are any bolts, that when installing your new lock, the heads are down flush and not stuck out where they can get in your way.
