The Stem Caster Carts are strong and versatile handling carts. Made with Supra Erectra Shelf wire shelving, these carts are set on four Metro casters for increased maneuverability. The open wire surfaces of the shelves prevent the accumulation of dust, allowing air to circulate freely; they also enable greater visibility. With no requirement of any tools, the cart can be assembled within minutes. The Super Erecta Shelf wire shelving can be changed quickly to suit your needs and the shelves are adjustable to intervals of 25 mm (1 inch) for the entire height of the post. The casters have donut bumpers of 89 mm (3.5"), are non-marking, and are available in rigid, swivel or brake types.
