Adjustable Cylinder Tail Piece for American Keyed Door Locks

Replacement Cylinder Tail Piece with Break Off Tabs

This replacement cylinder tail piece is specifically designed for American style keyed door cylinders that use a flat tail piece. It features 14 break-away score marks at 1/8" (3.2 mm) increments, allowing you to easily adjust the length to fit thinner doors up to 2-1/4" (57 mm) thick. With an overall length of 2-3/8" (60 mm), this tail piece offers compatibility and flexibility for a wide range of door thicknesses typically found in residential and commercial settings.

The tail piece installs by unscrewing the cylinder cap, carefully removing the key, and replacing your existing tail piece with this new one. The break-off tabs make it simple to customize the length for your specific door, reducing the chances of binding or improper cylinder function. Designed to work with American keyed cylinders that use a flat-style tail piece, it is a practical solution for maintenance, repair, or retrofit applications.
