Don-Jo FF-35 Frame 3.5" Hinge Filler Plate

The Don-Jo FF-35 Frame Hinge Filler Plate is a precision-engineered solution for "blanking out" unused hardware preparations in residential and light-commercial door frames. This 3.5-inch hinge filler is designed to fill the mortise (recess) in a door jamb when a hinge has been removed, relocated, or abandoned. By sealing the opening, the FF-35 restores the frame's smooth profile, ensuring a professional appearance and preventing the buildup of debris inside the hollow frame.

Sized at 3-1/2" x 1-1/4", this plate is an essential solution for door frame repair in apartment complexes, hotels, and office retrofits where standard 3.5" hinges are commonly used.
