What does a garage door strut do?

It is a metal reinforcement bar that runs horizontally across the inside of a door section. It stiffens the panel and resists bowing, cracking and hinge pull-out on wide or heavy doors.

Is 22-gauge strong enough for a double door?

22-gauge is a middle weight, stiffer than 24-gauge but lighter than 20- and 18-gauge struts. It works on many double doors, but very wide or heavy doors usually call for thicker steel or more than one strut per section.

How many struts come in a bundle?

60 struts per bundle. That covers several doors or a full set of sections on a large door, so check how many sections your door has before ordering.

Do the struts include screws or brackets?

No. The bundle is the struts only, so plan on self-tapping screws or the fasteners your door maker specifies.

Will a strut fix a door that is already cracking?

A strut can stop further bowing and spread the load at the hinges, but it won't repair a cracked panel or a failing spring. Inspect the springs, cables and track before adding reinforcement.

What size door section do these fit?

They are 8 feet long and 2-1/4 inches wide, sized for standard door sections. Measure your section width and the flat area inside the panel before mounting.
