STI STI-MBP1316 14 Gauge Backplate

Overview

The STI-MBP1316 is a 14 gauge steel backplate engineered to provide structural support and a secure mounting surface for STI electric strike installations. This accessory stabilizes the strike mechanism against the door frame, ensuring repeatable latching geometry and consistent fail-safe or fail-secure operation under load. Deploy this when installing an STI-EM151804 strike into a standard hollow metal or wood frame where a backing plate prevents the strike from flexing under repeated latch cycles.

Compatibility

The STI-MBP1316 is designed specifically for the STI-EM151804 electric strike and integrates with access control systems operating at 9VDC. The backplate accommodates standard door frame depths and provides the rigid mounting platform required to keep the strike mechanism aligned with the latch bolt path. Verify frame thickness and strike orientation (inswing vs. outswing) against your door assembly before ordering.

Installation Notes

Position the backplate behind the strike unit on the door frame exterior or interior (depending on your strike orientation and code requirements). Secure using standard fasteners appropriate to your frame material — masonry anchors for concrete or brick, wood screws for timber frames, or self-tapping fasteners for metal frames. Ensure the backplate sits flush against the frame to maintain strike-to-latch alignment. Do not overtighten fasteners, as this can distort the 14 gauge steel and throw off the striker geometry.
