Aluminum weld-on door and gate hinges with grease fittings, 2 pcs

Two aluminum weld-on hinges with grease fittings

This pair of aluminum hinges is intended for fabricated door, gate and ramp projects, including suitable trailer or truck applications. Each hinge has a three-knuckle barrel, flat welding leaves and a capped grease fitting on the middle knuckle. The leaves provide the surfaces for welding to the moving panel and its frame.

Plan the hinge position around your fabrication

Compare the barrel position and leaf arrangement with the joint you are building or repairing. Check panel clearance throughout its required movement, and allow access to the grease fitting after installation. A vehicle name alone cannot establish fit for a welded assembly.

Confirm the frame material before welding

Have the fabricator confirm the hinge and frame materials and select a suitable welding procedure. Direct welding of an aluminum hinge to a steel frame should not be assumed compatible. Establish the hinge size, number and spacing needed for the panel's weight and use before fabrication; a load rating is not supplied for this pair.

Overall dimensions, pin material and grease specification are not provided. Confirm those details where they affect your project. After installation, follow the fabricator's lubrication instructions and check that the hinges move freely without the panel contacting the frame.
