Don-jo 504FES Mortise Lock Wrap Around Plate Stainless

Product Description

The DON-JO 504FES is a mortise lock wrap around plate designed to reinforce the door edge at mortise lock cut outs. It installs over the existing 86 cut out to provide a clean, finished appearance while adding structural protection to the door face. Finished in stainless steel, this plate is built for durability in high-use environments. Measuring 12 inches in length and 2 inches in width, it fits standard door preparations and is installed by locksmiths, door hardware technicians, and finish carpenters during new installation or retrofit work.

This wrap around plate is suited for commercial and residential door applications where mortise lock hardware is used. It is particularly useful on replacement or retrofit installations where the existing door edge shows wear, damage, or an oversized cut out around the mortise pocket. The stainless steel finish makes it appropriate for high-traffic entryways, institutional facilities, and anywhere corrosion resistance or a consistent hardware finish is required.

Installation Notes

Installation is typically performed by a licensed locksmith or qualified door hardware technician. Before installation, ensure the door is stable and, where applicable, remove the door from the frame to allow full access to the edge. Fasten the plate using the appropriate screws for the door material, and verify alignment with the existing mortise lock body before securing fully. Refer to local building codes for hardware requirements on fire-rated or accessibility-compliant doors.
