The crate features 3/8 Inch round welded-bars with a cross bar to offer maximum inescapable stability. These bars give the crate the impact protection that makes it so heavy duty. The crate is lockable via a marine grade hardware latch that provides ultimate security. The locking latch locks into place automatically to provide hassle-free security.
Overview: This seventh best extra large dog crate has a single door and is made from five, seven, and nine-gauge mesh, making it very heavy-duty and durable. There are no tools required for assembly and its measurements are 49.5 inches long, 29 ½ inches wide, and 31 ¼ inches tall. There are three security locks on the door, eliminating the risk of easy escape. It is appropriate for pets weighing 85 pounds at most. The height of pets is recommended to be no taller than 30 inches.
The Smithbuilt cage is well established. It has a tried and tested track record of many customer reviews. So you can feel comfortable with what to expect. Beware of other cheap cages that do not have a good number of customer reviews. You’ll have less reason to have confidence in whether it’ll be suitable or a complete waste of money, or even dangerous for your pet.
Crates that don’t close securely are pretty worthless, so you’ll want to make sure that any crate you select has high-quality latches. But beware of crates with exceptionally large latching mechanisms, as some dogs will learn how to open the door themselves. If you have an especially escape-prone pooch, you’ll probably need a crate especially designed for Houdini dogs with double latches or more advanced locking mechanisms.
The reason this crate doesn't rank as highly as the Empire is that it's not quite as escape-proof. I think the top door might be a weak point, so you may want to use a zip tie to stop it opening if you don't plan on using it. The most determined and strongest chewers may be able to attack the bars though - so for these dogs look for sheet-walled crates instead.
So I pet sit and crates are a must for those who aren't potty trained so I have a crate in every size and shape. My last 48 broke from wear and tear so I got this one and the price is good but the cage is sort of flimsy. This wouldn't be a brand I'd recommend for anxious dogs or those who try to escape. I have many metal crates and some are stronger than others but I think this one is one of the weaker ones. Still serves its purpose for the calmer dogs who won't paw at it.
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.)
