These 3.5" casters have a 1.75" long stem threaded to 5/8"-11 and have a load rating of 250# each. This version has a fully locking mechanism (locks both the wheel rotation and swivel) These casters make an ideal match for either our ultimate theater base, or our collapsing base plates as they need no additional hardware to make a fully functional rolling boom base or truss tower.
