STI Kit Package - "B" Spacer for STI-1210B and - KIT-06297B

STI KIT-06297B Spacer Kit for STI-1210B and STI-1221B

Overview

The KIT-06297B is a spacer accessory designed to adjust installation clearance between door frame and strike assembly on STI-1210B and STI-1221B electronic locks. Use this when non-standard frame geometry or door thickness requires gap compensation to ensure proper strike alignment and credential reader operation. Typical deployment: retrofit installations on existing frames where standard mounting leaves gaps that prevent reliable strike engagement.

Compatibility

Compatible with STI-1210B and STI-1221B lock/strike assemblies. Operates at 9VDC. Integrates with HID credential reader systems paired to these strikes. Do not use with other STI series models or non-STI strike hardware.

Installation Notes

Spacer installation requires drilling 7mm fixing holes through frame material (masonry drill recommended). Position spacer frame centrally over the lock/strike assembly before marking hole locations. Secure with provided wall fixings. Cable gasket selection depends on your wiring system type—refer to the specific STI-1210B or STI-1221B installation guide for gasket and wiring routing. Verify 9VDC power availability at the strike before final assembly.
