STI KIT-G92099 Optional Gasket for STI-6520/6521/6522 Series
Overview
The KIT-G92099 is an optional environmental gasket designed to seal and protect the STI-6520, STI-6521, and STI-6522 series lock mechanisms from moisture, dust, and harsh outdoor conditions. This gasket extends the operational life of these 9VDC access control locks by preventing water ingress and environmental degradation at cable entry and mounting points — critical when installing in loading docks, exterior wall-mounted readers, or any location subject to rain, humidity, or direct spray.
Compatibility
The KIT-G92099 gasket is engineered specifically for the STI-6520, STI-6521, and STI-6522 series access control lock systems. Verify your exact lock model number before ordering; this gasket will not fit other STI families or third-party strike mechanisms. Installation with the correct lock model is mandatory for proper environmental sealing and operational integrity.
Installation Notes
Position the gasket over the device mounting surface and cable entry points before securing the lock frame. Use a 7mm masonry drill bit for wall-mounted installations. The gasket sits between the lock body and mounting frame, so ensure all cable entries are routed through the gasket apertures to maintain environmental protection. Surface-mounted installations may require spacer inserts to blank off unused cable entry holes and prevent environmental bypass.
