STI BPP4836 EnviroArmour Polycarbonate Back Panel

Overview

The BPP4836 is a polycarbonate back panel designed to mount and protect STI strike assemblies in outdoor and high-moisture environments. The EnviroArmour polycarbonate construction delivers impact resistance and weather tolerance — meaningful when your strike hardware faces direct sun, rain, salt spray, or temperature swings that degrade standard steel mounting plates over time. This accessory solves the durability problem for facilities where strike frames corrode or crack within 2–3 years; the polycarbonate substrate and integrated gasket design extend service life and reduce maintenance cycles.

Compatibility

The BPP4836 integrates with STI strike systems operating at 9VDC. Verify compatibility with your specific strike model by cross-referencing the strike assembly documentation; this back panel is designed as a mounting and environmental barrier for standard STI strike hardware. It does not modify electrical operation or voltage requirements — it is a mechanical and protective accessory only.

Installation Notes

Mount the back panel using the four fixing holes (7mm masonry drill bit recommended for masonry or concrete surfaces). Secure the frame to the wall with the wall fixings provided. Position any required weather gaskets over the device before securing the frame to prevent water ingress at cable entry points. For surface installations on non-masonry substrates, verify the fastening method matches your wall type (wood, metal stud, composite).
