The Duralast 1/2" Drive 24" Ratcheting Breaker Bar features a 45-tooth ratcheting head with an 8-degree swing arc to turn fasteners. The ratcheting breaker bar also features a 180-degree swivel head and a reversing collar for switching between clockwise and counterclockwise directions. The ratcheting breaker bar is convenient for tire change applications by not requiring the removal of the sockets from the lug nuts after each turn. Finally, the full-polish finish allows for easy cleaning and provides corrosion resistance.
