Understanding Struts

Struts are horizontal steel reinforcements that attach to the back of your garage door panels. They prevent bowing and add rigidity.

Top Strut (Opener Reinforcement)

The most critical strut. Reinforces the top panel where the opener bracket attaches. Required for opener installation on most doors.

Prevents top panel from bending
Distributes opener force across panel
Usually 1-1/2" or 2" tall
Must span full door width

Mid-Panel Struts

Additional struts for middle panels. Common on wider doors (16'+) or doors showing signs of bowing.

Prevents wind damage on wide doors
Corrects existing panel bow
Adds rigidity to lightweight panels
Recommended for hurricane zones

When You Need Struts

Signs your door could benefit from strut reinforcement:

Installing a new opener
Visible panel bowing
Door wider than 14 feet
Wind-prone or hurricane area
Non-insulated steel panels

Measuring for Struts

Getting the right size strut is simple. Here's what you need to know.

Length = Door Width

Measure your door opening width. Struts come in standard sizes: 8', 9', 10', 12', 14', 16', and 18'. Order the size matching your door.

Height Options

Standard struts are 1-1/2" or 2" tall. Taller struts provide more rigidity. For most residential doors, 1-1/2" is sufficient.

Not Sure? Ask Us

Call with your door width and what you're trying to accomplish. We'll recommend the right strut for your situation.

About Perforated Angle

Perforated angle (also called slotted angle or punched angle) is versatile steel hardware with pre-drilled holes for easy mounting.

Track Hanging

Supports horizontal tracks from ceiling joists. Adjustable mounting positions let you fine-tune track alignment.

Opener Mounting

Create custom brackets for opener installation. Works great when ceiling joists don't align with your opener.

Custom Brackets

Build custom solutions for unique installations. Can be cut to length and bolted together at any angle.

Reinforcement

Brace framing, reinforce jambs, or add structural support wherever needed around your garage door system.

DIY Tip: Installing Struts

Strut installation is a manageable DIY project. Work with the door down and disconnected from the opener. Position the strut horizontally across the panel, centered on the panel's height. Use self-tapping screws (typically #10 x 3/4") through the strut holes into the panel. Space screws every 12-18 inches. For opener reinforcement struts, attach the opener bracket through both the strut and the panel for maximum strength.
