STI BPP1816 Polycarbonate Back Panel 18" × 16"

Overview

The STI BPP1816 is an 18" × 16" polycarbonate back panel designed to shield access control readers and mounting hardware from environmental exposure and accidental impact. Polycarbonate construction provides impact resistance and weather protection without obscuring device functionality—critical in high-traffic entry points, outdoor vestibules, and areas where weather or vandalism pose a risk to exposed reader installations. The BPP1816 fits standard access control door control infrastructure and integrates with STI system deployments requiring protective back-panel mounting.

Compatibility

The BPP1816 is sized to accommodate standard access control reader frames and mounting layouts within the STI product family. It operates on 9VDC, aligning with typical STI access control power supplies. Verify mounting footprint alignment with your specific reader model before installation—back-panel compatibility depends on exact reader dimensions and mounting hole positions. Check the reader datasheet or contact your integrator for dimensional cross-reference if you are pairing this with non-STI hardware.

Installation Notes

Mounting requires four fixing holes drilled through substrate (masonry or metal stud). Use a 7mm masonry drill bit for concrete or brick installations. Secure with appropriate wall anchors rated for your substrate type. For surface-mounted readers, use gaskets to seal unused cable entry holes and prevent water ingress. Ensure adequate clearance behind the panel for wiring runs and reader depth—polycarbonate thickness is approximately 3–4mm, so account for this during rough-in planning. Allow for reader accessibility during maintenance; do not over-torque fasteners into polycarbonate mounting points.
