摘要 A tool for measuring and marking conduit entry holes in a distribution box. The tool includes a rectangular ruler having a short edge attachment groove proximal to a short edge of the ruler which is configured for engagement by a locking assembly. The tool further includes a handle having a tip face and a side face, and a side face locking assembly that is slidably engaged into the short edge attachment groove. Engagement of the side face locking assembly into the short edge attachment groove couples the handle to the ruler and facilitates the measurement and marking of a depth dimension and a lateral location of one or more conduit entry holes on the distribution box.
