Instructions

Difficulty: Moderate

Things You’ll Need:

Carriage bolts (optional--you can use the bolts that come with the bracket)
Drill
Washers
Locking nuts
Socket wrench and socket
Pencil
Ladder

Step1

Mark where the bracket for an electric door will go in the garage door. Center the bracket on the top middle of the door.

Step2

Place the bracket on the center mark and draw marks for the bolt holes. Make sure that the bracket is facing the right way. Usually the brackets are labeled so you know which way is up.

Step3

Use an existing hole if you are replacing an existing bracket for an electric garage door. You still might have to make marks for three of the bolt holes.

Step4

Drill a hole for the bottom of the bracket. If you are using an existing bolt hole, just skip to the next step.

Step5

Hold the bracket in its place on the door and insert the first bolt from the outside of the door to the inside. You will have to reach your hand to the outside of the door to do this effectively.

Step6

Tighten the nut by hand after slipping on the washer, and then snug it a little more with the socket wrench. In this way, the bracket will stay in place and you don't have to hold it up while you drill the other holes. Since a common problem with brackets is coming loose due to the vibration of the mechanism and the door, you might want to use a carriage bolt that goes completely through the door in combination with a locking nut and washer.

Step7

Align the bracket for an electric garage door properly. Drill a hole for the top bolt.

Step8

Insert a carriage bolt, and snug the nut with the socket wrench.

Step9

Repeat the process for the remaining two bolts and nuts, drilling and inserting the bolt one at a time to ensure the bracket remains perfectly straight.
