STI KIT-06297D Electric Strike Spacer Kit
Overview
The KIT-06297D is a spacer accessory for the STI-1210D and STI-1221D electric strike systems. This component solves a common installation problem: ensuring correct door frame offset and strike alignment when mounting electric strikes on varied frame depths. A spacer kit addresses door frame variations (wood, metal, or composite) that would otherwise force the strike body out of square or create gaps that compromise latch engagement. The 9VDC operating voltage integrates directly with the strike system's power circuit — no separate supply needed.
Compatibility
The KIT-06297D is engineered specifically for STI-1210D and STI-1221D electric strike models. These strikes are commonly deployed in access control systems paired with HID readers and credential platforms. If you are installing an STI-1210D or STI-1221D and need to compensate for frame thickness or mounting surface variation, this spacer kit is the correct accessory. Do not use this kit with other strike families — compatibility is frame-specific.
Installation Notes
Installation requires positioning the spacer between the strike body and the door frame to establish proper alignment. Drill holes using a 7mm masonry bit (per STI installation guidance). Secure the spacer with the provided fasteners before mounting the strike assembly. Ensure the spacer does not interfere with the latch throw or bolt path — verify clearance before final tightening. The kit accommodates both surface and recessed mount scenarios common in commercial door frames.
