On the budget end of the price range is the Smithbuilt self-proclaimed ‘Heavy Duty Dog Crate.’ This industrial looking dog crate is crafted using high-quality steel to make a strong, durable crate that will prove inescapable for a dog and will last for many years. The front door is locked with two slide bolt latches, and the top opening is secured with one. There have been reports that the locking mechanism is weak and can be hugely improved with a standard padlock bought separately. Smithbuilt has made this crate fade, rust, and corrosion resistant by covering it with a multi-layer finish that is better than the powder coat paints on other brands of a dog crate.
If you want the very best escape proof crate with no exceptions, then this impact dog crate is it. The Impact Case Stationary represents the ultimate indestructible dog crate. Made in the USA from high quality and durable .063 aluminum makes this crate incredibly strong as well as being lightweight and easy to move. This crate is corrosion resistant and will last a great many years making it a sound investment. This is especially important considering dogs can live for up to 2 decades. IATA compliant for airline travel!
Overview: This crate has a single door and is foldable, which is convenient for travel. It is made with a satin-black Electro-Coat finish and the tray is plastic and washable. The bolt is a sliding latch and there is a divider panel located for keeping waste elimination on one side and sleeping in the other. There are no tools required for setup. The dimensions are appropriate for dogs between 71 and 90 pounds, with 42 x 28 x 30 inch measurements. The iCrate brand actually makes this cage in sizes for smaller dogs, so this is the largest they have.
Most Helpful review (read the full Amazon review): “I needed to know how much this weighed and one listing stated it was 48.8 Lbs I'm not very trusting of website descriptions so I weighed myself and then held the kennel (not easy) and the difference was 43.7. Also to make this airline approved you need to buy metal nuts for the bolts instead of the plastic ones that come with it. You might also need to drill holes in the rear. This is plenty big for my 95 Lb lab mix. He fit in an XL but…“
Addendum added January 28, 2013: My vet had never noticed these carriers because I had never put one up on the exam table until my last vet visit. She looked at it with interest and totally concurred with my opinion of having a small, but open carrier for my two (panicky) cats. She has seen more than a few overheated pets in too enclosed carriers. Since I live far from the vet I always carry spare towels for the bottoms of the carriers and she found that the "stable floor covering'* I use was an additional comfort feature for my pets long trip to their appointments. (I just ordered the larger size of this carrier for my "Phat Kat" and will donate her previous carrier to our local animal shelter.)
