The Aluminum Crate Trolley floor is made from solid tread-brite aluminum, giving it a non-slip surface. The floor has a welded lip-edge to prevent crates from sliding off the cart. The trolley has a swivel & pivot tongue for easy maneuvering. The T-shaped handle is removable and retracts under the cart for storage. The trolley's lightweight aluminum construction and pneumatic tires makes this cart easy to pull.
