Taller and Longer than the ZIN4000P, the PROFESSIONAL line of Zinger aluminum dog boxes are designed to be the most secure and safest of the Zinger dog crates.The difference between Zinger Deluxe models and the Professional models has to do with its heavy duty door construction. As an added layer of security in the Professional series Zinger has added a secondary Backup Locking Plate behind the lock so that the dog cannot get his teeth into the latch at all. This size will accommodate labs, boxers, shepherds, pit bulls. Fits dogs up to 120 pounds.
