Product Description

The BEST 711128350 is an extra heavy full surface hinge designed for demanding door installations where both leaves mount directly to the face of the door and frame rather than being mortised in. Built from steel with a plain finish, this hinge measures 4 inches in height and 4 inches in overall width, with a door leaf width of 2 inches and a frame leaf width of 2 inches. The non-removable pin adds a layer of security by preventing the hinge pin from being driven out from the exterior side. Leaf thickness is 0.139 inches and pin diameter is 0.27 inches. Licensed contractors and door hardware installers working on commercial or heavy-duty residential applications are the primary installers for this type of hinge.

This hinge is suited for full surface mounting on heavy-duty door applications where mortising is not practical or desired. The extra heavy duty rating makes it appropriate for high-traffic commercial doors, institutional settings, or any application requiring a more robust hinge than a standard weight unit. Its 4 inch by 4 inch nominal size is a commonly specified configuration for commercial-grade door openings.

Key Features

  • Full surface mount — no mortising required on door or frame
  • Extra heavy duty construction in steel for high-traffic applications
  • Non-removable pin design for added door security
  • 4 inches by 4 inches nominal size with 2 inch leaf widths
  • Leaf thickness of 0.139 inches for rigid, low-flex performance
  • Plain finish suitable for field painting or use in utility applications

Compatibility

Designed as an OEM-style full surface hinge replacement for commercial and heavy-duty residential doors requiring a 4 inch by 4 inch nominal hinge with full surface mounting.

Installation Notes

Installation is typically performed by a licensed door hardware technician or commercial contractor. Before installation, ensure the door is properly supported and secured to prevent movement during fastener driving. Use fasteners appropriate for the door and frame material — do not overtighten into hollow-core substrates. Verify local building and fire codes for hinge quantity and placement requirements on rated door assemblies.
