Model PR4000: 21"W x 24"H x 30"L

• Deluxe Versus Professional models – The differences
  between our standard Deluxe models and our top of the line Professional
  crates has to do mainly with its heavy duty door construction. On any
  crate the door is consistently the weakest point and "Houdini" dogs
  typically target this area in their attempt to escape. In the
  Professional series we have reinforced the door with extra bars, welds
  and bracing. As an added layer of security in the Professional series we
  have added a secondary locking plate to the door frame and to add extra
  value we also include a set of Heavy Duty Handles. Each door has a full
  length piano hinge and can be mounted to open left or right. The
  Professional line of aluminum dog boxes are designed to be the most
  secure and safest of the Zinger crates.
• Strong and Lightweight,
  Zinger aluminum dog crates offer incredible strength at one third the
  weight of steel. Unlike plastic and wire crates which easily crack and
  bend and need to be frequently replaced, Zinger crates are built to last
  a lifetime.
• Aluminum Construction – ZINGER™ crates are
  constructed from lightweight aircraft grade aluminum which is known for
  its durability and strength. Aluminum crates are perfect for dogs who
  often destroy or break out of plastic and wire crates. While built to be
  strong and secure, Zinger crates are light enough to be handled by one
  person with little effort.
• Lockable Slam Latch – Each
  door comes with a flush mounted slam latch which is keyed for added
  security while you are away from the crate. Rest assured that someone
  cannot simply open the crate and walk away with your dog. Made from
  strong "stainless steel" for durability and to prevent corrosion.
• Ventilation –
  A Zinger crate is fully vented down each side and along the back wall
  to provide maximum comfort for your dog. Our open design allows air to
  pass freely thru the door aided by the triple rows of lower and upper
  vent holes which surround the crate. By its very nature aluminum quickly
  dissipates heat making it a great material to construct dog crates
  provided there are enough air holes. Lots of adequate venting ensures
  your dog will remain safe while in its crate.
• Airline Travel Approved
  – ZINGER™ crates exceed the strength and ventilation requirements by
  most airlines. When ordered as an option our "Airline Rails*" the crate
  can be used to ship a dog by air. Strong aluminum crates will not bust
  or be broken by rough handling or shifting cargo loads thereby safe
  guarding your dog on route. When shipped in a Zinger crate your dog is
  protected.
• Stainless Steel Hardware – Lock and mounting hardware are made from stainless steel to eliminate rusting and corrosion.
• Modular Design
  – All ZINGER™ crates can be coupled side by side or stacked atop one
  another to form multiple dog crate systems or kennel banks.
• Beautiful Finish
  – ZINGER™ crates are finished in a durable “Silver Hammertone” powder
  coat both inside and out. The secret to this tough finish is the high
  temperatures in which it is "baked on" so that it will not wear off. By
  powder coating the inside as well as the outside it protects your dogs
  coat from discoloration. Coat discoloration is common when a dog sits in
  an untreated aluminum crate. The bare aluminum oxidizes and the residue
  rubs off onto the dog resulting in a grey silvery color. This will not
  happen in a Zinger crate.
• Super Solid Doors – Reinforced
  with solid bars and welded for extra strength the door is built to hold
  your "Escape Artist". A full length piano hinge and striker plate is
  standard and the door can be easily reversed to allow left or right hand
  opening.
