Don-jo EL103DU Full Lip Strike Dark Bronze Extended Lip

Product Description

The DON-JO EL103DU is a full lip strike designed for use with mortise and cylindrical locksets in commercial and residential door frames. The strike features a 2-1/4 inch standard lip alongside a 3 inch extended lip, allowing it to bridge frames where the door stop is set deeper than standard. Finished in dark bronze, it blends with oil-rubbed and dark-tone hardware families. The unit ships as a single piece and is intended for installation by locksmiths, door hardware technicians, or finish-trade carpenters working door hardware rough-in and trim-out.

This strike is suited for interior and exterior door applications where an extended lip is required to properly capture the latch bolt across a wider frame stop or when replacing a worn or damaged OEM strike. The dark bronze finish is appropriate for matching dark-tone lever and handleset hardware in both light commercial and residential settings. Installation requires standard door hardware tooling and proper frame prep.

Installation Notes

Installation should be performed by a qualified locksmith or door hardware technician. Power tools are not required, but a sharp chisel and mallet are typically used for mortising the strike plate into the door jamb. Ensure the door is in the closed and latched position before marking strike location for accurate alignment. Verify that the existing jamb mortise depth is compatible with the strike profile before fastening.
