STI STI-1200CR Stopper II Flush Mount Door Strike
Overview
The STI-1200CR is a Stopper II® flush-mount door strike assembly without integrated horn, configured for custom label application. This is the strike mechanism you deploy when you need a discreet hardware footprint in access control installations — the flush geometry minimizes frame protrusion and lowers the risk of accidental activation during normal door passage. The custom label option supports facility branding or tenant identification without field modification. Use this where card readers, keypads, or biometric systems control a single point of entry and the strike hardware must integrate seamlessly with the frame.
Compatibility
The STI-1200CR integrates with standard 12V/24V access control power supplies and conventional door strike wiring harnesses deployed in commercial entry-control systems. Before ordering, verify your door frame depth and strike pocket dimensions — flush-mount designs require precise alignment with existing frame routing to avoid binding or gaps that compromise strike release under load. Confirm custom label dimensions and adhesive compatibility with your door material (aluminum, steel, or wood frame) during specification to ensure proper adhesion and visibility.
Installation Notes
Mount the strike assembly flush into the door frame pocket using corrosion-resistant fasteners rated for your door material. Route all wiring through conduit or the strike's integrated strain relief to prevent pinch or abrasion damage during operation. Test strike release under load after installation to confirm proper alignment and sufficient clearance — binding indicates misalignment that will cause control system nuisance faults or field service callbacks. Polarity is denoted by color band marking on the strike body; verify correct wiring sequence (cathode end identified by band) before energizing to avoid incorrect control behavior.
