Built for the mission, not the living room. The Collapsible Crate – Pro Series was designed in direct collaboration with U.S. special forces operators and military canine handlers who demanded more from their equipment. It features high-anxiety-sized ventilation on the rear half of the crate, a reinforced bar door, upgraded uniform latches, and a Line-X coated top panel that gives working dogs a non-slip surface in any environment. Additional drainage holes make field cleaning fast and simple. Available in 30", 34", 40", and 40”+ it folds flat, sets up fast, and delivers a level of durability and security built for professionals who can't afford failure. 30" | Medium - (30.5"L x 20.5"W x 26"H) 34" | Intermediate - (34.5"L x 23"W x 29"H) 40" | Large - (40.5"L x 23"W x 29"H) 40"+ | XL - (40.5"L x 27"W x 33"H)
