STI STI-6522-S Bopper Stopper Biometric Reader Cover
Overview
The STI-6522-S is a hinged polycarbonate protective cover designed to shield biometric readers, keypads, and access control devices from vandalism and environmental damage. Molded from super-tough polycarbonate with a stainless steel torsion spring hinge, this cover keeps the reader accessible during normal use while blocking accidental or intentional strikes. The closed-position spring mechanism ensures the cover stays down when not in use, protecting the biometric sensor and keypad buttons from ice, snow, dirt accumulation, and direct impact — common failure points in high-traffic or outdoor access control installations.
Compatibility
The STI-6522-S fits biometric readers, keypads, electrical outlets, push buttons, smaller-sized pull stations, volume controls, and lighting switches. It is compatible with standard access control systems using fingerprint or PIN-entry readers. Verify exact mounting clearances with your biometric reader's footprint and bezel dimensions before ordering, as cover opening dimensions vary by model size. The cover integrates with door control infrastructure that supports credential-based entry.
Installation Notes
Fast, easy installation using included mounting hardware and gasket. The hinge is factory-installed; secure the cover frame to the wall or door frame using the provided screws. Polycarbonate operating temperature range is −40°F to 250°F (−40°C to 121°C) — suitable for indoor and non-freezing outdoor deployments. STI recommends gasket replacement after five years of service to maintain environmental sealing. No special tools required beyond a screwdriver.
