Don-jo MEST158630 Mortise Extended Lip Ansi Strike

Product Description

The DON-JO MEST158630 is a mortise-type extended lip ANSI strike plate finished in satin stainless steel. Strike plates of this type seat into the door frame mortise and receive the latch or deadbolt thrown from a mortise lockset, keeping the door securely closed. The extended lip design provides additional coverage for offset or thick-stop frames where a standard lip would leave the latch bolt exposed. At 4-7/8 inches in length and 1-5/8 inches in width, this strike is sized for commercial and institutional door hardware applications. Locksmiths, door hardware installers, and commercial carpenters are the primary trades handling this component.

This strike is suited for interior and exterior door frames in commercial, institutional, and multi-family residential construction where mortise locksets are specified. The extended lip configuration is commonly required on hollow metal frames with pronounced door stops or where frame geometry does not allow a standard strike to fully protect the latch bolt. The satin stainless steel finish provides corrosion resistance in high-traffic or humid environments such as healthcare, hospitality, and institutional corridors.

Installation Notes

Installation is performed by a licensed locksmith or qualified door hardware installer. Power is not required, but the door and frame should be fully de-latched and the door held open before removing or installing the strike. Fastener holes should be aligned to the existing mortise pocket in the frame; do not enlarge the pocket beyond the manufacturer-prepared dimensions. Work on fire-rated door assemblies must comply with the applicable listing requirements and local building code.
