The OTC 7485 Locking Collar Wrench creates a better way to move steering rack components without disassembly, ultimately making service faster and easier for technicians. The wrench features an eccentric cam design and split-circle, which opens to wrap around and securely close on steering components. The 1/2" square-drive cam automatically adjusts the lobe to the diameter of the bar, creating maximum leverage and a secure grip to position and maneuver components during vehicle service. The Locking Collar Wrench can be used on steering linkage, small-diameter exhaust and other pipes that need to be adjusted or repositioned.
