#3 Garage Door Replacement Hinge – 18 Gauge for Sectional Overhead Doors

This #3 hinge connects adjacent garage door sections and supports the roller at the door’s side edge. It allows the sections to pivot as the door travels through the track while maintaining the roller offset required at a #3 hinge position.

Use it to replace a worn, bent, or cracked hinge on a compatible sectional garage door requiring an 18-gauge #3 hinge.

PRODUCT DETAILS

• Hinge number: #3
• Thickness: 18 gauge
• Type: Sectional garage door end hinge
• Function: Connects door sections and supports the roller stem
• Typical position: Between the third and fourth sections, counting from the bottom, on doors using a standard graduated hinge arrangement

WHAT DOES THE #3 MEAN?

The hinge number identifies its roller offset, not its thickness. Numbered end hinges position the rollers at different distances from the door sections to match the track arrangement.

Always match the original hinge number and door manufacturer’s requirements. A #1 or #2 hinge should not replace a required #3 hinge.

COMPATIBILITY

Suitable for sectional overhead doors designed to accept this hinge style, number, and gauge. Before ordering, compare:

• Number stamped on the existing hinge
• Mounting-hole spacing and hinge dimensions
• Roller-stem fit and roller offset
• Door manufacturer’s required hardware thickness

18-gauge material is thinner than 16-, 14-, or 11-gauge material. Do not use this hinge to replace heavier hardware unless the door manufacturer approves the substitution.

Specialty doors, proprietary hinge systems, and unusual track configurations may require different hardware. Compatibility depends on the door hardware, not the opener brand.

INSTALLATION NOTES

Inspect the surrounding door section, mounting holes, and roller before replacing the hinge. A new hinge cannot correct damaged reinforcement, stripped mounting holes, or track misalignment.

Use the fasteners specified for the door and confirm that the hinge pivots freely and the roller moves without binding after installation.

SAFETY

Disconnect opener power and secure the door against movement before servicing. Keep fingers clear of section joints and hinge pivot points.

Do not loosen springs, lift cables, or cable-connected bottom brackets during hinge replacement. If the door is off track, damaged, or difficult to move, have a qualified garage door technician inspect it before operating.
