Solid-steel 22" threaded rod welded to a female reciever that accept either our scaffolding caster wheels or our base plates. Allows for individual adjustment of each leg in conjunction with a scaffolding caster wheel allowing your scaffold to roll on uneven surfaces. Can additionally be converted to a level jack when used with a base plate in place of the caster wheel. Cold-dip zinc galvanized. See our video at the bottom of the page for more information on the benefits of scaffolding jacks.
