Definition
A horizontal metal reinforcement bar bolted across the inside of a garage door section to stiffen it. Struts keep wide doors from sagging or folding when the opener pulls from the center, and they matter most on double-car doors and doors rated for wind load. If your door bows visibly when it runs, or a section has creased after a windstorm, adding or replacing struts is often part of the fix Door Serv Pro recommends.
