Final answer:
The square in the middle of the bending shoe is not used to hold the pipe bender on the wall.
Step-by-step explanation:
False. The square in the middle of the bending shoe is not used to hold the pipe bender on the wall. The bending shoe is a tool used in plumbing or electrical work to bend pipes and conduit. It is used to create precise bends in the pipe, allowing it to fit into a specific installation area without impairing the flow of fluid or electrical current.
