Narrow 16-inch wide steel deck is ideal for busy aisles, or 24-inch for more loading capacity. Six-wheel design is fully maneuverable with two 8 " x 2 " rigid center wheels, and for 5-inch corner mounted swivel casters with ball bearing wheels. All wheels are non-marking polyurethane tread for added maneuverability. Two removable pipe handles extend 48 " above the deck for taller loads, which mean fewer trips.
