STI STI-1286 Strike Backplate for Electric Locks
Overview
The STI-1286 is a replacement strike backplate engineered for STI-9711 and STI-9714 electric lock systems. Operating at 9VDC, this component serves as the mounting and alignment foundation for strike mechanisms within door frames. It ensures precise positioning and retention of the strike hardware — critical for reliable latch-bolt engagement and repeatable lock operation across thousands of cycles. Deploy this backplate when replacing worn strike hardware or integrating new STI strike assemblies into existing door frame installations.
Compatibility
The STI-1286 is purpose-built for STI-9711 and STI-9714 electric strike locks. Verify your existing strike model before ordering — cross-model mounting will not work. Integrates with standard 9VDC access control power supplies and wiring already in place for compatible STI strike installations. Do not attempt retrofit to non-STI strike hardware or different voltage systems.
Installation Notes
Mount the backplate to the door frame using standard fastening hardware appropriate to your frame material (wood or metal). Ensure the backplate sits flush against the frame surface to maintain proper strike alignment with the keeper on the strike edge. Verify 9VDC continuity from your access control power supply before final installation. No special tools required beyond standard screwdrivers and a level.
