Don-Jo SMEST-104 Extended Lip Schlage Mortise Strike

The Don-Jo SMEST-104 is a heavy-duty extended lip mortise strike engineered to align with Schlage-prep mortise lock installations where a standard ASA strike box falls short of the jamb stop. Don-Jo Manufacturing builds the SMEST-104 from non-ferrous material at 13 gauge (.095), delivering a robust, corrosion-resistant strike face that holds up in high-traffic commercial and institutional doorframes. The plate measures 4" wide × 4-7/8" tall, with the critical 4" lip dimension measured from the center of the screw hole to the end of the lip — the specification that matters most when matching frame depth and door stop thickness. Two latch holes accommodate the dual-latch bolt pattern common to Schlage mortise hardware. The SMEST-104 is available in three finish options — 630 satin stainless steel (US32D), Duranodic dark bronze (Don-Jo DU), and 622 flat black (US19) — making it straightforward to coordinate with existing door hardware finishes in commercial, multi-family, and institutional applications.

SMEST-104 Extended Lip Mortise Strike — Key Features

• Extended Lip Design: 4" lip (center of screw hole to lip end) bridges the gap between mortise lock faceplate and jamb stop on deeper commercial frames.
• Heavy-Gauge Construction: 13 ga. (.095) non-ferrous material provides a rigid, durable strike face suited for demanding commercial door cycles.
• Schlage Mortise Compatibility: Latch hole layout is cut to match the dual-latch bolt pattern of Schlage mortise lock preparations, making this a direct replacement or new-installation fit.
• Dual Latch Holes: Two latch hole openings accommodate both the latchbolt and deadlatch (auxiliary latch), maintaining full mortise lock function.
• Three Commercial Finishes: 630 satin stainless steel, Duranodic dark bronze (DU), and 622 flat black (US19) give specifiers coordinated finish choices across a broad range of hardware schedules.
• Overall Strike Plate Size: 4" × 4-7/8" face fits standard ASA strike cutouts while the extended lip reaches beyond the door stop.
• Non-Handed: No handing required — a single SKU installs on any handing without modification.
