My 70 pound dog put his weight against the bottom of the kennel and pushed the chain link away from the bottom of the frame and escaped in under 5 min.  BIG WASTE OF MONEY.  The chain link is put so that it is on the OUTSIDE  of the frame thus making escape easy - this was not anchored or welded to the frame so escape was VERY EASY.  This was put together well.  No mistakes. THIS IS A VERY POORLY ENGINEERED PRODUCT which by the way  takes many hours to put together.
