1" Drive Heavy Duty Power Breaker Knuckle Bar Total Length 40" Swivel Head

Bought this for changing wheels on a motorhome. Broke wheel nuts loose that were torque to 500 ft pounds. Extra length of this item makes it easier to break the nuts loose. A+

Good bar and plenty strong enough for most light commercial jobs. The bearing locks the head at 90degrees firmly enough. One niggle is the small grub screw that seems to loosen up after a short while. This allows the head to detatch from the chrome bar. Not a massive issue , just dont carry it head down. But for the price I give 5* .
