What is the term for the actuator attached to the rear of a cylinder and used in various locking mechanisms?

Shim
Tail Piece
Shear Line
Ward

The correct answer is: Tail Piece

The term for the actuator attached to the rear of a cylinder that is utilized in various locking mechanisms is known as the tailpiece. A tailpiece is an essential component found in both mortise locks and cylindrical locks, serving as a connector between the locking cylinder and the locking mechanism itself. When the key is turned in the cylinder, the tailpiece rotates, which then interacts with the locking mechanism to either lock or unlock the door. Each of the other options refers to different elements within locksmithing. A shim is a thin piece of material used to adjust the spacing or position of components and can sometimes be used to bypass locks in certain contexts. The shear line is the correct alignment where the pin and cylinder need to separate to allow for the lock to turn, but it does not refer to a physical component attached to the cylinder. A ward, on the other hand, refers to a specific design feature within a lock that prevents the use of incorrect keys, but like the shear line, it does not describe an actuator. Understanding the function of the tailpiece is important for recognizing how various locking systems operate and aids locksmiths in repairs and installations.
