Sure there are 13 vibrant hues to choose from, but teachers, school administrators and librarians are also won over by the Gorilla Truck’s multi-functionality and super strength. Load these trucks with 600 lbs. of books, equipment, art supplies, student work, and just about anything else - they’re ready to go to work anywhere in your school. Another feature people love: the fixed middle casters that allow the truck to pivot on an axis. This makes it easier to raise the leading casters over thresholds and into elevators, even when the truck is fully loaded. Need to make tight turns? The Gorilla Truck does it with little effort. Because the Gorilla Cart spins on center wheels, accessing both sides in narrow isles is a breeze. 5" dual wheel caters with soft tread ensure quiet, smooth-rolling operation. Available with 6 sloping shelves, 4 sloping shelves and 1 flat base shelf, or 3 flat shelves. Overall measurements: 18"d x 36"w x 44"h.
