Combine the mobility of a cart with the versatility of a step ladder with our Stockpicker Trucks. Convenient spring loaded step ladder holds the cart securely in place while a person is standing on the ladder. Crutch tip ladder prevents the cart from moving while stocking. Springs then return the ladder to the raised position once personnel exit the step. All shelves have a 2" lip turned up to prevent items from falling off. Standard casters are 4" by 2" mold-on-rubber, two rigid and two swivel with wheel brakes. Steel units are powder coated blue.
