STI KIT-405440 Gasket for STI-6514 Electric Strike
Overview
The KIT-405440 is a replacement gasket assembly for the STI-6514 electric strike operating at 9VDC. This accessory restores weatherproofing and frame seal integrity on existing strike installations where the gasket has degraded or requires replacement during maintenance cycles. Install this when you need to extend the operational life of an STI-6514 unit without full strike replacement.
Compatibility
This gasket is engineered exclusively for the STI-6514 electric strike. It is not cross-compatible with other STI strike models or third-party strike systems. Confirm your installed strike model before ordering — the KIT-405440 will not fit strikes outside the STI-6514 family.
Installation Notes
Gasket replacement requires removal of the existing strike assembly from the door frame. Position the new gasket over the strike mounting surface, then secure the strike frame over the gasket using the provided fasteners. Ensure the gasket sits flush against the door frame to prevent water or dust ingress, especially in exterior or high-traffic door applications. No special tools are required beyond standard fastening equipment.
