Practical Use Scenarios
-
Retrofit thicker door frames — When the door frame is too deep for a standard ES110 faceplate, this extension lip allows proper alignment without modifying the door/frame.
-
Improve frame sealing coverage — In installations where there’s a gap or recess between strike and frame, the extension lip closes that gap for a clean finish.
-
Upgrade existing door hardware — If replacing an electric strike but retaining the door geometry, the lip bridges difference in thickness.
-
Commercial or high-traffic access control — Ensures reliable locking alignment even after prolonged use, thanks to durable materials.
