Don-Jo EST-115 Extended Lip ASA Strike – 13 Gauge, 4-7/8" | Satin Stainless, Dark Bronze, Flat Black

The Don-Jo EST-115 is a heavy-duty extended lip ASA strike engineered for commercial and institutional door frames where a standard-length strike box won't reach the latch bolt on time-delayed or deeply set closers. Don-Jo Manufacturing stamps this extended lip ASA strike from 13 gauge (.095) steel, giving installers and specifiers a plate that holds its shape under repeated latch engagement without the deflection common to lighter-gauge hardware. The strike measures 1-1/2" wide by 4-7/8" tall, with the critical note that the 1-1/2" lip dimension is taken from the center of the screw hole to the end of the lip — the measurement that actually determines frame-prep compatibility. A single latch hole accommodates standard cylindrical latch bolt geometry. Three finish options are stocked on this listing: 630 satin stainless steel (US32D) for corrosion-sensitive or stainless-hardware pairings, Duranodic dark bronze (Don-Jo DU) for dark aluminum storefront and hollow metal frame installations, and 622 / US19 flat black for contemporary or powder-coated frame applications. Whether you are replacing a worn factory strike, upgrading frame reinforcement on a wood or hollow metal frame, or specifying new construction with offset latch geometry, the EST-115 delivers a purpose-built ASA extended lip strike in a contractor-friendly shelf pack of five.

EST-115 Extended Lip ASA Strike – Key Features

• Heavy 13 Gauge (.095) Construction: Thicker-than-standard steel resists deformation during latch engagement, providing long-term alignment on high-cycle commercial doors.
• Extended 4-7/8" Lip Profile: The extended lip accommodates latch bolt reach on doors with deeper jamb offsets or where standard 4-7/8" ASA strike geometry is required by frame prep.
• Precise 1-1/2" Lip Measurement: Lip width measured from center of screw hole to end of lip — spec the strike to your frame prep with confidence and avoid field-fit surprises.
• Single Latch Hole: Sized and positioned for standard cylindrical latch bolt compatibility across common prep patterns.
• Three Finish Options on One Listing: Choose 630 satin stainless (US32D), Duranodic dark bronze (DU), or 622 flat black (US19) to match the frame finish and hardware schedule without sourcing a separate SKU.
