Garage Doors and Parts – A garage door strut is a metal bar used to strengthen door panels. Most struts run horizontally across each section. They’re commonly found in double-wide doors. They prevent flexing when the door moves. Struts also support the door during strong winds. Many doors include at least one top strut from the start. Extra struts may be added later for safety or reinforcement. The length of the strut depends on door width. It usually spans the full panel length. Some struts are installed at the factory. Others are added during repairs or upgrades.
Your door may start to sag in the middle. You might hear creaking sounds when it opens. The door could look slightly bent. These are signs your strut isn’t doing its job. Loose screws or brackets also suggest a weak strut. The top section may rattle more than usual. The door may look uneven while closing. Gaps may appear between panels when closed. Strut repairs should be done before other parts break. If ignored, the damage can spread across the door. Always inspect for wear at least twice a year.

You’ll need a power drill or screwdriver. Use a socket wrench for tight bolts. Bring metal screws or bolts for securing. Safety gloves and goggles are also important. You’ll need a new strut if the old one broke. Use a ladder to reach the top panels. A tape measure ensures the new strut fits. Some installations may need a metal saw. Prepare everything before starting the repair. Having all tools ready saves time and avoids injury. Clean the area before installing the new strut.
First, disconnect the garage door opener. This keeps the door from moving while you work. Open the door manually to mid-height. Use clamps to hold it open safely. Start removing bolts from the damaged strut. Take off any brackets attached to the strut. Gently pull the strut away from the panel. Don’t bend or force the metal. If screws are stuck, apply oil to loosen. Once removed, inspect the panel underneath. Check for damage caused by the broken strut. Wipe the area clean before moving on.
Measure the panel’s width using a tape. Cut the strut if it’s longer than needed. Make sure all holes align with existing slots. Drill new holes if none line up. Use a metal file to smooth cut edges. Lay the strut flat along the panel. Double-check alignment before bolting. Mark each hole with a pencil. Prepare screws or bolts nearby. Avoid scratching the panel with tools. Set the strut aside after prepping.

Hold the strut in place with help or clamps. Insert bolts through the end brackets first. Tighten the bolts using a socket wrench. Start from one end and move across. Check that the strut lies flat against the panel. Add center brackets if included. Double-check all screws for tightness. Reattach anything removed earlier. Shake the panel slightly to test strength. Listen for any unusual noise. Adjust bolts if movement is heard.
Remove clamps holding the door open. Slowly lower the door by hand. Watch for smooth motion from top to bottom. Listen for grinding or creaking. Open and close the door a few times. The motion should be smooth and even. Reconnect the garage door opener. Use the remote to operate the door. Watch the panel for any flexing. If flexing occurs, check bolt tightness. Confirm the strut is firmly attached. Make small adjustments if needed. The door should now feel more stable.
Inspect the strut every six months. Tighten bolts that feel loose. Clean off any rust using a wire brush. Lubricate moving parts around the strut. Replace damaged brackets right away. Avoid slamming the door closed. Keep the strut free of dirt and moisture. Store tools in a dry area nearby. Repaint rusted struts if needed. Track any signs of bending over time. Report strange noises early. Fix issues quickly to prevent door failure.
Always disconnect the opener before repairs. Never remove struts with tensioned springs nearby. Use a helper for long struts. Wear gloves when handling metal. Avoid over-tightening bolts, which can crack panels. Read the door manual for guidelines. Don’t use damaged tools while working. Use proper ladder placement at all times. Keep kids and pets away during repairs. Dispose of broken struts properly. Double-check every bolt after finishing. A well-installed strut improves your garage door’s lifespan. Repairs should be done early to avoid major issues. Follow each step carefully for the best results.
