Profiled cylindrical measuring instrument for reading the fitting length of a door security lock locking cylinder has a cross-sectional profile to suit a locking cylinder casing and reading elements with a linear scale gradation.

摘要

A rod-shaped basic body (1) has a cross-sectional profile corresponding to a locking cylinder casing, as well as one or more reading elements with a linear scale gradation (2) and line rule. This body also has a cylindrical profiled part (3) and a bridge section (5) that is symmetrical to a center longitudinal line (4). This bridge section has two side sections (6) running parallel. The body is also designed with a threaded hole (7) to take a lock casing screw.
