Don-Jo SMEST-115 Extended Lip Mortise Strike – Schlage Prep, 13 Ga. Non-Ferrous, Three Finish Options
The Don-Jo SMEST-115 is a heavy-duty extended lip mortise strike engineered for frames prepped to accept a Schlage mortise lock chassis. Don-Jo Manufacturing produces this ASA strike in 13 ga. (.095) non-ferrous construction, giving specifiers and locksmiths a substantial, deflection-resistant plate where a standard-lip mortise strike simply will not reach the latch bolt. The face plate measures 1-1/2" wide × 4-7/8" tall, with the critical 1-1/2" lip dimension measured from the center of the mounting screw hole to the end of the lip — the spec that confirms frame-to-door-edge alignment on wider stop conditions. Two latch holes accommodate the dual-bolt geometry common to Schlage mortise hardware. DoorwaysPlus carries this extended lip mortise strike in three finishes: 630 satin stainless steel (US32D), Duranodic dark bronze (Don-Jo DU), and 622 / US19 flat black — select the finish that matches the existing frame hardware or architectural specification.
SMEST-115 Extended Lip Mortise Strike — Key Features
- Extended Lip Geometry: 1-1/2" lip (center of screw hole to lip end) bridges the gap between frame edge and latch bolt on frames where a short-lip ASA strike falls short.
- Heavy 13 Ga. (.095) Construction: Non-ferrous plate stock at 13 gauge provides a rigid, durable bearing surface suited to high-cycle commercial mortise lock applications.
- Schlage Mortise Compatibility: Cut to the Schlage mortise prep pattern, making this the correct replacement or new-construction mortise strike for frames already routed for Schlage mortise hardware.
- Dual Latch Holes: Two latch holes match the dual-bolt configuration of a mortise lock chassis — latch bolt and deadbolt engage properly without additional modification.
- Standard ASA Strike Face: 1-1/2" × 4-7/8" face fits standard ASA cutouts; no upsizing of the frame pocket required when replacing an existing mortise strike of the same pattern.
- Three Commercial Finishes: Available in 630 satin stainless steel (US32D), Duranodic dark bronze (DU), and 622 flat black (US19) to coordinate with architectural door hardware specifications.
- Convenient Shelf Pack: Sold in a shelf pack of 5 — practical for locksmiths and hardware distributors stocking multiple finish options.
