The Metro 4 Super Adjustable Wire Cart is designed for efficiency and versatility, featuring four super adjustable wire shelves, four 63" tall posts, and four 5" polyurethane casters. Its open layout enables rapid loading and unloading from all sides, with shelf adjustability at 1" intervals along the posts for optimal flexibility. Each 5" polyurethane caster can support up to 300 pounds, allowing the cart to safely handle a total load of 1,200 pounds. The casters are made with durable, abrasion-resistant, non-marking, and shock-absorbing polyurethane tread, making the cart suitable for various settings. Additionally, each caster is equipped with a donut bumper to protect walls and doors from damage. The cart also includes four pairs of shelf clips per shelf to ensure secure placement and enhanced stability.
