The Beta Tools 1/2" Drive Ratchet with Extendable Shaft, No. 920/55L, offers a twist-n-lock mechanism that allows the shaft to stay in place without movement. The shaft length features seven locking positions, and is extendable from 11" to 16.5" long. Extending the ratchet to its maximum length gives users 70 percent more reach, leverage and torque, according to the company. Beta Tools uses the same sliding forward/reverse switch as the company's other signature ratchets.
