Don-Jo MEST-102 Extended Lip Mortise ASA Strike — Satin Stainless, Dark Bronze & Flat Black

The Don-Jo MEST-102 is a 13-gauge (.095) non-ferrous extended lip mortise ASA strike engineered for commercial and institutional doors that require a full-lip mortise strike in the standard 2" × 4-7/8" ASA footprint. The 2" lip is measured from the center of the mounting screw hole to the end of the lip — the industry-standard callout specifiers and door hardware distributors use when detailing a mortise-prep door frame. With a single latch hole and heavy 13-gauge construction, the MEST-102 is a direct-fit extended lip mortise strike replacement for mortise lockset preps on hollow-metal and wood frames where added lip depth keeps the latch fully captured at maximum door gap. Three finish options are stocked for this listing: 630 satin stainless steel (US32D), Duranodic dark bronze (Don-Jo DU), and 622 / US19 flat black — covering the most commonly specified commercial hardware finishes in a single SKU family.

MEST-102 Mortise Strike Features

• Mortise Strike Format: Designed for mortise lockset door preps requiring a standard ASA strike cutout with an extended lip to bridge the gap between door edge and frame rabbet.
• Extended 2" Lip: The 2" lip dimension (center of screw hole to lip end) ensures the latch bolt is guided and retained even on doors with greater than typical clearance at the frame.
• Heavy 13-Gauge Construction: At .095" wall thickness, the MEST-102 delivers commercial-grade rigidity suitable for high-cycle mortise lockset applications.
• Non-Ferrous Material: Corrosion-resistant non-ferrous construction pairs with the available stainless and coated finishes for long-term appearance and performance.
• Standard 4-7/8" ASA Height: Matches the universal ASA strike height used across major mortise lockset manufacturers, simplifying direct replacement and new-construction specification.
• Single Latch Hole: One latch pocket accommodates the primary latch bolt of a mortise lock, keeping the strike profile clean and frame-prep requirements minimal.
• Three Commercial Finishes: Satin stainless steel (630/US32D), Duranodic dark bronze (DU), and flat black (622/US19) coordinate with the most widely specified commercial door hardware finish schedules.
• Shelf Pack of 5: Packaged in quantities of five, making the MEST-102 practical for multi-door projects or distributor stocking.
