STI KIT-H18019 Standoff Kit for Metal Protective Cabinets
Overview
The KIT-H18019 is a standoff mounting kit engineered for metal protective cabinet installations where credential readers and strike mechanisms require proper spacing and mechanical isolation from cabinet surfaces. This kit addresses the common installation challenge of mounting access control hardware directly to sheet metal — improper standoff distance can cause electromagnetic interference, mechanical vibration transmission, and mounting stress on reader terminals. The kit operates at 9VDC, matching standard lock and strike power requirements in cabinet-based access control deployments.
Compatibility
This kit is designed for metal cabinet applications paired with HID-compatible reader and strike configurations. The standoff design accommodates standard access control reader mounting footprints and integrates with typical cabinet-mounted strike assemblies used in secure equipment enclosures, server room access panels, and protective storage cabinets. Verify cabinet material thickness and reader terminal layout before ordering — standoff length must accommodate both the reader face and any weatherproofing gasket behind it.
Installation Notes
The kit includes mounting hardware sized for 7mm anchor holes drilled through cabinet panels. Use masonry or metal drill bits appropriate to your cabinet gauge — thin-gauge steel cabinets may require self-tapping fasteners or threaded inserts rather than standard wall anchors. Ensure the reader wiring route clears the standoff arms when the frame is installed; cable strain can loosen fasteners over time. The 9VDC supply line should run in conduit or cable tray separate from any AC power to minimize noise on the credential signal path.
