SUITABLE FOR MULTIPLE PETS: The product is 48 inches long, 30 inches wide and 33 inches high. The dog crate is made of reinforced steel tubing with a diameter of 0.87 inches, which is stronger and more durable than thin wire crates. This is a very sturdy large dog crate that can be used even for strong and aggressive dogs. SAFETY COATING: This dog crate features a multi-layer hammered green protective coating that resists rust and corrosion, so it can be used both indoors and outdoors. In addition, the frame coating is non-toxic, so it won't harm your dog even if he chews or licks the cage frame. ROLLING CASTERS: 360-degree rolling casters allow you to easily move the kennel around your home, two of the wheels with brakes for a secure hold. SAFETY LOCKING BOLT: The double upgraded bolt lock design of the large dog crate prevents your dog from getting cranky and avoiding damage or injury. The double door design of the dog crate is not only convenient for dogs to enter and exit, but also easy to interact with and feed your dog. REMOVABLE DISCUSSION: The dog crate comes with two removable discs, a washable metal tray and a floor grate to make clean up easier. Most parts of the dog crate are pre-assembled, all you need to do is finish the rest without walking, which takes less than 10 minutes.
