STI STI-MBP0506 14 Gauge Backplate for Electromechanical Strike

STI STI-MBP0506 14 Gauge Backplate for Electromechanical Strike

Overview

The STI-MBP0506 is a 14 gauge steel backplate engineered to reinforce and stabilize STI electromechanical strike installations at the door frame. This accessory addresses a critical installation requirement: providing solid mechanical backing for strikes that must withstand repeated impact loads from users pushing against doors. A flimsy or undersized backplate invites frame flex, misalignment, and premature strike failure. The 14 gauge thickness delivers the structural rigidity needed in high-traffic commercial access control deployments where the strike sustains constant mechanical stress.

Compatibility

The STI-MBP0506 is designed for use with STI electromechanical strike models, including the STI-EM07123.5 and STI-EM08073.5 families. Verify the specific strike model number against the STI compatibility matrix before ordering — backplate geometry and bolt hole spacing must align exactly with your strike unit. Installation into the door frame requires standard masonry or wood-stud mounting depending on your frame construction.

Installation Notes

Mount the backplate to the door frame using the four fixing holes, aligned with the strike unit. A 7mm masonry drill bit is the standard recommendation for pilot holes in concrete or brick frames. Secure with appropriate fasteners for your frame material — concrete anchors for masonry, wood screws for timber frames. Verify that the backplate sits flush against the frame surface to avoid binding the strike mechanism. The unit is rated for 9VDC operation as part of a complete access control circuit; backplate itself is passive and carries no electronics.
