STI BPF1816 EnviroArmour Fiberglass Back Panel

Overview

The STI BPF1816 is an 18" × 16" fiberglass back panel designed to provide a durable, weather-resistant mounting substrate for access control components in demanding environments. EnviroArmour® construction delivers corrosion and weather resistance without sacrificing structural rigidity — a practical choice when you're mounting readers, strike assemblies, or credential hardware on exterior walls or in salt-spray, high-moisture, or UV-exposed locations where standard steel backing fails or requires constant maintenance.

Compatibility

The BPF1816 integrates with STI access control systems and lock/strike assemblies that require a solid mounting surface. Operates at 9VDC, aligning with standard low-voltage access control infrastructure. Consult your strike or reader documentation for specific mounting hole patterns and fastener requirements — fiberglass back panels are typically sized to accommodate universal 4-hole or bracket-mount configurations common across commercial access control product lines.

Installation Notes

Mount using corrosion-resistant fasteners (stainless steel or nylon-insert hardware recommended for outdoor or high-moisture environments). Drill pilot holes to prevent cracking in the fiberglass. For outdoor installations, seal all fastener penetrations with weather-resistant sealant or gaskets to prevent water ingress behind mounted components. The 18" × 16" form factor fits standard single-gang and dual-gang electrical box cutouts on most commercial building facades. Allow clearance behind the panel for wiring bundles and cable entry hardware.
