Don-jo FF45PC Filler Plate Frame Hinge Cut Out Prime Coat

Product Description

The DON-JO FF45PC is a steel filler plate designed to cover vacant hinge cut-outs in door frames. When a frame is prepared for a hinge that is no longer required, or when a frame is reused in a new application with a different hinge count, this plate fills the mortise opening flush to restore a clean, finished appearance. The plate measures 1.65 inches wide by 4.5 inches long and arrives in a prime coat finish ready for field painting. At 0.3 pounds, it is a lightweight single-unit component sold individually. Door hardware installers and locksmiths are the primary trades working with this part.

This filler plate is suited for commercial and institutional door frame applications where hollow metal frames have been over-mortised or where hinge locations have changed during a retrofit or renovation. It is also used in new construction when a pre-cut frame does not match the final hardware schedule. The prime coat finish makes it compatible with most field-applied paints used on hollow metal frame assemblies.

Installation Notes

Installation is typically performed by a door hardware installer or commercial locksmith. The filler plate is secured into the existing hinge mortise of the door frame using appropriate fasteners for the frame material. Ensure the frame surface is clean and free of paint build-up before seating the plate to achieve a flush fit. Prime coat finish should be painted after installation to match the surrounding frame finish.
