Gently Used Furrari Dog Kennel / Crate SUPER Thick Plastic - Lots of Air Vents, and Very Thick Metal Door. The Door can be opened from either side (left and right) (2 spring open/closed bars, 1 on each side) Please see photos here. Door can also be completely removed without disassembling the kennel. 2 plastic close clamps are missing - but unless your dog is Houdini - it works well without them. This brand of kennel - for this size - is well over $140 retail. This one can go for $50. Medium Sized: 27" Long x 20" Wide x 19" High Metal Screws can be purchased to make this kennel even more secure for travel. Pls see screw holes in photo here ...
