Constructed from select kiln-dried northern hardwoods then molded to a full 7/8" thickness. Countersunk bolt holes provide a smooth working surface and all dollies include standard 3" non-marking polyolefin swivel casters with 900 pound capacity. Kiln-dried hardwood dollies can be used for a variety of loading applications. Selected hardwood helps prevent warping and shrinkage. The wood sealant and countersunk bolt-holes on these furniture dollies provide a smooth working surface. Our equipment dollies are supplied with four ball-bearing swivel casters for portability. Choose open or solid deck dollies. Wheel dollies with carpets or rubber bumpers help protect cargo during transport.
