The DON-JO EL102DU is a full lip strike designed for use with cylindrical locksets in commercial and residential door applications. The strike features a 2-1/4 inch full lip and a 2 inch extended lip, providing additional door frame protection and a clean, finished appearance when the door is closed. Finished in dark bronze, it blends with standard dark-finish door hardware. The unit ships individually and is sold as a single piece. Licensed locksmiths, door hardware installers, and finish carpenters are the typical trades that install this component.
This full lip strike is suited for interior and exterior door applications where an extended lip is required to protect the door stop from latch bolt contact. It is commonly installed in hollow metal frames, wood frames, and commercial door assemblies where standard short-lip strikes do not provide adequate frame coverage. The dark bronze finish coordinates with oil-rubbed bronze and dark-finish locksets commonly used in commercial and multi-family residential construction.
Designed as an OEM-style replacement or new-installation full lip strike for cylindrical lockset applications requiring an extended lip configuration.
Installation is typically performed by a licensed locksmith or door hardware installer. Before installation, ensure the door is secured in its closed position and all latch bolt alignment is verified against the existing frame prep. Use a chisel and drill appropriate to the frame material to mortise the strike plate flush with the frame face. Follow applicable building and fire code requirements for rated door assemblies when replacing hardware on fire-rated doors.
