Do not waste ur money on this. The metal is cheap. Put together with zip ties. Not enough of them. The person who put mine together did not zip tie bottom unbeknownst to me and my dogs were out and gone within 30 min. It says it's galvanized steel but it bends like aluminum. My dog bent it by sticking his nose through it. I would return if I still had the box but someone put it together for me while I was out of town and discarded the box.
