Abstract
A rigid magnetic tag line safety tool is an apparatus that allows a user to guide and connect to a steel plate as it is placed onto or removed from a trench. The rigid magnetic tag line safety tool includes a handle bar, an electrically insulative shaft, a universal joint, a stator, and a magnetized rotor. The handle bar allows a user to grip the apparatus. The handle bar is positioned perpendicular to the electrically insulative shaft and is mounted adjacent to the first shaft end. The electrically insulative shaft distances the user from the steel plate. The stator is pivotably mounted to the second shaft end by the universal joint such that the present invention is not hindered by the varied path of a steel plate being positioned onto or removed from a trench. The magnetized rotor is rotatably mounted to the stator and attaches to the steel plate.
