This butterfly style weld-on door hinge is designed for trailer door and ramp door applications where a compact weld-on hinge is needed. The hinge includes a grease fitting for lubrication and has a raw steel finish suitable for welding and finishing after installation.
Weld-on hinges should be test-fit before welding so door swing, hinge spacing, and clearance are correct.
Compatibility: Verify before ordering. This hinge is measurement-based and should be matched to the door, frame, and weld area.
Vehicle / System Fit: Commonly used for trailer ramp doors, utility doors, service doors, and fabricated steel door assemblies.
Installation Notes: Confirm door alignment, hinge spacing, weld access, and swing clearance before final welding.
Performance Insight: A greaseable hinge helps reduce dry hinge noise and improves serviceability over a non-greaseable hinge.
