I wish I could give this zero stars- the pieces to hold the sliding door in place and lock it are not properly measured and do not function at all. The door can be pushed open from the inside and my dog immediately figured out how to do this. Wayfair customer service was absolutely horrendous when I contacted them about this- they sold a faulty item and provided completely impersonal and frustrating customer service without an actual resolution. My own fault for buying a cheap piece of furniture- if you actually need a dog crate that serves the intended purpose I strongly urge you to shop elsewhere.
