PARK TOOL - AV-1 - AXLE VICE
This tool holds the axle so it will not turn while work is done on the hub. It has two different diameter receptacles so it will work on front and rear axles. Aluminium jaws will not damage axle threads. It is simple to use - just insert the axle into the proper diameter opening and tighten the bench vice. The jaws will open automatically when the vice is opened.
