Don-Jo EST-103 Extended Lip ASA Strike — 13 Gauge, 3" x 4-7/8"
The Don-Jo EST-103 Extended Lip ASA Strike is a heavy-duty 13 gauge (.095) strike plate engineered for doors where the standard ASA strike opening sits deeper in the frame than a conventional strike can bridge. Don-Jo Manufacturing produces this extended lip ASA strike with an overall height of 4-7/8" and a 3" lip measured from the center of the screw hole to the end of the lip — the critical dimension specifiers and locksmiths use when matching a strike to frame depth and door prep. A single latch hole accommodates the spring latch or deadlatch of a cylindrical lockset. The EST-103 is available in three finish options: 630 satin stainless steel (US32D), Duranodic dark bronze (Don-Jo DU), and 622 flat black (US19) — making it a practical finish-match for a wide range of commercial and architectural hardware schedules.
EST-103 Extended Lip ASA Strike — Key Features
- Extended Lip Design: 3" lip (center of screw hole to end of lip) fills the gap on deeper-set frames where a standard ASA strike falls short.
- Heavy 13 Gauge Construction: Formed at .095" thickness for a rigid, commercial-grade strike that holds its shape under repeated latch engagement.
- Standard ASA Strike Format: 4-7/8" overall height conforms to the conventional ASA strike footprint, fitting existing frame cutouts without modification in most applications.
- Single Latch Hole: One latch opening sized for the spring latch or deadlatch of a standard cylindrical lockset prep.
- Three Finish Options: Available in 630 satin stainless steel (US32D), Duranodic dark bronze (Don-Jo DU), and 622 flat black (US19) to coordinate with door hardware finish schedules.
- Sold in Shelf Packs of 5: Packaged in quantities of five, convenient for contractors and service locksmiths stocking common replacement and new-construction hardware.
