This is just like every other wire crate except for one thing and it's the most important thing! On EVERY kennel I have purchased the sliding lock was shaped like a sideways "L". You slide it over, then roll the bar down and the end of the "L" locks the "lock into place" holding the door closed. On this crate, it is a simple straight bar that you slide over. If your dog is the sort that will try to get out or starts barking and jumping at the door, (due to hearing someone outside), the latch can side open. Why modify a part that works to something that doesn't work. How much money do you save by leaving a 1" piece of round bar off? And here we have it again folks, the price goes up, quality goes down.
