Don-Jo DEST-103 Extended Lip Dimple ASA Strike – Satin Stainless, Dark Bronze & Flat Black

The Don-Jo DEST-103 is an extended lip dimple ASA strike engineered to reinforce the keeper pocket on hollow-metal frames and wood frames wherever a standard short-lip strike leaves the latch bolt exposed to manipulation. Don-Jo Manufacturing produces the DEST-103 with a pressed dimple in the strike cup that accommodates the latch bolt without requiring a routed or chiseled pocket in the frame, making it a practical choice for both new installations and retrofit work on frames that lack a full mortise pocket. The strike measures 3" wide × 4-7/8" tall, with the 3" lip measured from the center of the screw hole to the end of the lip — a critical dimension specifiers should confirm against frame-prep depth before ordering. Three finish options are stocked on this listing: 630 satin stainless steel (US32D), Duranodic dark bronze (Don-Jo DU), and 622 / US19 flat black, allowing the strike to coordinate with a wide range of lever, knob, or handleset trim. A note on gauge: Don-Jo's product page currently lists 18 ga. (.050); however, Don-Jo's 2026 Strike-Plates catalog specifies 13 ga. (.095) for the DEST series. We source the heavier 13 ga. figure from the catalog and note the discrepancy — please confirm gauge with Don-Jo directly if your specification is gauge-sensitive.

DEST-103 Extended Lip Dimple Strike — Key Features

• Dimple Cup Design: The pressed dimple in the strike face accepts the latch bolt without requiring a routed pocket in the door frame, simplifying installation on frames with shallow or no mortise prep.
• Extended 3" Lip: The long lip (measured from screw-hole center to lip end) bridges the gap between the frame face and the latch bolt throw, providing continuous coverage that a short-lip ASA strike cannot match.
• ASA Strike Pattern: Conforms to the standard ASA strike footprint, allowing drop-in replacement of worn or undersized factory strikes without redrilling the frame.
• Heavy-Gauge Construction: Catalog-specified at 13 ga. (.095), the DEST-103 is built for commercial hollow-metal and heavy-duty wood-frame applications where frame integrity and long-term cycle performance matter.
• Three Commercial Finishes: Available in 630 satin stainless (US32D), Duranodic dark bronze (DU), and 622 flat black (US19) — finish designations that map directly to common architectural hardware schedule entries.
• Non-Handed: The DEST-103 is not handed and installs on either hand of door without a separate SKU.
• Shelf Pack of 10: Sold through the shelf pack for contractor and facility quantities, reducing per-unit cost on multi-opening projects.
