Don-Jo SMEST-103 Extended Lip Schlage Mortise Strike

Don-Jo Manufacturing built the SMEST-103 extended lip mortise strike for commercial and institutional door frames that call for a full 4-7/8" ASA strike with a 3" lip measured from the center of the screw hole to the end of the lip. At 13 gauge (.095) non-ferrous construction, this mortise strike delivers the frame reinforcement specifiers demand on high-traffic openings where a standard-lip strike simply does not reach. Two latch holes accommodate the bolt geometry of Schlage mortise locksets, making it a direct replacement fit for frames originally prepped for that hardware family. The SMEST-103 ships in your choice of three finishes: 630 satin stainless steel (US32D), Duranodic dark bronze (Don-Jo DU), and 622 flat black (US19) — giving designers and locksmiths the coordination options commercial projects require.

SMEST-103 Extended Lip Mortise Strike — Key Features

• Extended 3" Lip: Lip dimension measured from center of screw hole to end of lip, bridging deeper frame rabbets where short-lip ASA strikes fall short.
• 4-7/8" ASA Strike Height: Full ASA footprint seats cleanly in standard ASA-routed commercial door frames without additional mortising.
• 13 Gauge (.095) Non-Ferrous Construction: Heavier gauge than light-duty residential strikes, suited for commercial door hardware schedules.
• Two Latch Holes: Geometry matched to Schlage mortise lockset bolt/deadbolt spacing as a compatibility and replacement fit.
• Three Finish Options: 630 satin stainless steel, Duranodic dark bronze, and 622 flat black allow finish coordination across a full hardware schedule.
• Sold in Shelf Packs of 5: Convenient pack quantity for multi-opening commercial projects and locksmith shop stock.
