Best 711420750 Full Mortise Hinge 3.5in Steel Chrome

Product Description

The BEST 711420750 is a full mortise specialty hinge designed for standard door installations requiring a clean, flush-mounted look. Built from steel with a chrome-plated finish, this square-corner hinge measures 3.5 inches in both door leaf height and overall width, with a leaf thickness of 0.099 inches. It is mortised into the door edge and frame, creating a concealed mount that sits flush with the door surface. Installation is typically performed by carpenters, door hardware specialists, or general contractors working on commercial or residential door assemblies.

This hinge is suited for full mortise door applications where the hinge leaves are recessed into both the door and the frame. The chrome-plated steel construction makes it appropriate for interior doors in commercial settings, institutional buildings, or residential projects where a polished chrome appearance is specified. The 3.5-inch size is a common standard dimension for interior passage doors.

Installation Notes

Full mortise hinges require a routed or chiseled mortise pocket in both the door edge and the door frame to seat each leaf flush. A router with a hinge template or a sharp chisel and mallet are the standard tools for this work. Ensure the door is properly supported and the mortise depth matches the leaf thickness before fastening to avoid binding. Follow applicable building codes for door hardware installation in commercial or rated-assembly applications.
