The SmithBuilt 48″ Extra Large Heavy-Duty Dog Crate Cage is a commercial-quality metal cage that is perfect for keeping your dog or other animals secure and comfortable. This cage features a 3/4″ frame reinforced with 1/2″ diameter (20 gauge) welded steel tubes for top to bottom strength and durability. The front door locks with two slide-bolt latches, and the crate top with one. The cage also includes four wheels for easy transfer from room to room and has a grated design that allows for any soiling to drop to the lower pan to maintain a clean environment for your pets. The bottom pan features an integrated lip around the perimeter to contain any mess from spilling outside the kennel. The trays are held securely in place by a retaining latch, but can easily slide out from the bottom for easy and convenient cleaning.
