Caster Wheels, 3 Inch Casters Set of 8, Threaded Stem 3/8"-16 x 1 (Screw Diameter 3/8", Length 1") Polyurethane Locking Swivel Casters,Heavy Duty Castors with Brake Wheels for Furniture and Workbench

I added the casters to the stands (Amazon), it does good, plus I can move it wherever I want to, even outside if need be with ceiling pull down or extension cord.
