STI EF8POST Fiberglass Corner Post Kit
Overview
The EF8POST is an 8-inch-depth fiberglass corner post kit designed to reinforce and protect electronic lock and strike hardware at door frame corners. Built with STI's EnviroArmour fiberglass construction, it resists weather, UV exposure, and physical impact — eliminating the frame rot and rust problems that plague wood or uncoated steel installs in semi-outdoor or high-humidity environments. This kit solves the integration problem when you're mounting electronic locks or strikes on older frames, exterior service doors, or loading dock entries where structural integrity and corrosion resistance matter.
Compatibility
The EF8POST is compatible with STI electronic lock and strike systems operating at 9VDC. It integrates with standard electronic access control hardware and power supply ecosystems. Confirm your specific lock and strike model against the STI product family before ordering — the corner post kit provides the structural foundation, but the strike and lock hardware must match your access control panel's voltage and signaling requirements.
Installation Notes
The 8-inch depth accommodates standard door frame corner geometry on hollow metal and wood frame doors. Installation requires drilling into the frame for fastening — verify frame material (wood, metal, or composite) and use appropriate fasteners. Mask off the installation area and use a 7mm masonry or wood drill bit depending on substrate. Apply the fiberglass post kit over the lock and strike area to provide structural enclosure and weather sealing. Ensure all unused cable entry holes are sealed with the inserts provided to prevent water infiltration. No special tools beyond standard drill and fastener kit are required.
