Zinger Heavy Duty Series – as strong as it gets! The overall look of this crate says it all. Nothing but a solid, heavy duty crate. Its side panels are made using 1 x 1 aluminum tubing with .100 thickness. The door is built of solid 3/8 aluminum bars inserted through 3/4 x 3/4 aluminum tubing. Each are then double-welded for unmatched strength. The top, bottom and back panels are made from .065 aluminum sheet that has been laser cut, formed and welded to exacting specifications. On any crate, the door is consistently the weakest point. If your dog is a Houdini-caliber escape artist, he or she will know that this is the area to exploit in order to escape. To avoid this risk, in the Heavy Duty model, Zinger has reinforced the door with extra bars, welds and bracing. Why buy Zinger? Unlike plastic and wire crates which easily crack and bend (and need to be frequently replaced), Zinger crates are built to last a lifetime . If your dog is frequently destroying or breaking out of plastic and wire crates, Zinger is the way to go. Heavy-Duty Aluminum Construction with Stainless Steel Hardware Zinger crates are constructed from aircraft-grade aluminum, prized for its durability and strength, while still being light weight. Zinger aluminum crates are ideal for dogs prone to destroying or breaking free of cheaper plastic and wire crates, which tend to easily crack, bend, and break. In addition, the lock and mounting hardware are made from corrosion- and rust-resistant industrial-grade stainless steel. Safe & Comfortable Zinger crates are fully vented down each side and along the back wall to provide maximum comfort for your dog. The open design allows air to pass freely through the door. Further, by its very nature aluminum quickly dissipates heat, making it an ideal material for a dog crate. Lots of adequate ventilation ensures your dog will remain safe and comfortable while in the Zinger crate. Versatile & Easy to Handle All Zinger crates have a modular design and can be coupled side by side or stacked atop one another to form multiple dog crate systems or kennel banks. Also, while built to be strong and secure, Zinger crates are one third the weight of similar but heavier steel crates and can easily be handled by one person, with little effort. Exquisite Powder Coat Finish Zinger crates are finished in a durable Silver Hammertone powdercoat 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. Importantly, the powdercoating on the inside as well as the outside of the crate protects your dogfts coat from discoloration as well. (Coat discoloration is unfortunately very 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. ) Secure Inside and Out From the inside, the crate is strengthened with solid bars and welded for extra strength. A full-length piano hinge and striker plate is standard and the door can be easily reversed to allow for left- and right-hand opening. From the outside, 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. The lock is made from stainless steel for strength, corrosion prevention and overall durability.
