Pet Cargo Crate Extension for Giant Crate

Do you have a tall dog? Does it meet the requirements to fit in a giant crate except that your dog's head or ears touch the ceiling of the crate? The 700Plus Kit is what you need that will address this problem.

This extension will keep your crate in compliance with IATA regulations and your dog in compliance with airline regulations. 

The 700Plus® Kennel Extension Kit will add a little more than 5 inches to the height of your existing Sky Kennel 700 Giant, Vari Kennel Giant 700, or Aspen Giant 700. As an example, if your Sky Kennel crate outside dimensions are 48"L by 32"W by 35"H, then adding the crate extensions will bring the height to 40.5".

Note that the extensions do not affect the length or width of the crate, only the height.

You should always confirm with your airline that your pet's crate will fit in their cargo opening. This is extremely important as not all aircraft cargo holds can handle this size pet crate.

Note the return policy at the end of this page.

So, how will the door that comes with your crate fit with the new extensions, you ask? Problem solved: this product comes with another door that will fit with the extensions!

The extensions are all installed easily by hand; no tools or hardware are needed or required. Simply add the two metal rails in between the top and bottom of the crate, install the new, bigger steel door, and thread the provided 6" bolts with metal washers through the existing kennel bolt holes and secure with the reinforced Metal Thumb Nuts. Everything you need to install the extensions are provided in the kit.

700Plus Kit Includes:

(3) Ventilated Metal Rails (left, right, back)

(18) 5.5" Bolts

(18) Washers

(18) Solid metal Thumb nuts

(1) NEW Larger size Metal Grated Door

The 700Plus Kit does NOT include a giant pet crate. If you have carefully measured your dog and need this size crate, click here for the giant pet crate.

The extension kit will add about 16.5 pounds to the existing XL Kennel weight (43 pounds) for a total of 59.5 pounds.


Before getting this extension kit, you must confirm with your airline that your pet's crate, including the extensions, will be acceptable for the cargo opening on the aircraft that serves your specific route. This is extremely important!!

    Posted by Deborah on 28th Jan 2019

    On November 4th, 2018 I placed an order for the Pet Cargo Crate Extension for Giant Crate (SKU CRT-EXT-700). This was my first time ordering not only a dog crate, but also extensions for the crate. Despite the many weeks of research, I was a bit nervous about an online purchase for a crate and extenders that would be suitable for our Great Dane/South African Mastiff mix (named Chibo). My husband and I have been living in a small eastern African country called Malawi that is not known for having a dog-loving culture. Stores with dog crates of any kind are non-existent, let alone a giant dog crate. We wanted to take advantage of a visit home to the U.S. for the holidays to purchase a crate for Chibo for our eventual move from Malawi. I measured Chibo up and down numerous times and read every blog I could find about traveling with large breeds dogs (which is how I stumbled upon the Pet Travel Store website) before making the purchase. After an ordeal dealing with the airlines to transport an oversided and overweight box, we finally have finally managed to receive and put together the crate with the extenders and are happy to share that not only were the extenders a perfect fit for our Petmate Sky Kennel 48" L x 32" W x 35" H, they were also a perfect fit for Chibo. I wanted to share my gratitude for your line of work. Without those extenders, we would not be able to travel with our boy. We were impressed by the quality of the product and the impeccable fit to the crate, alongside the superior customer service of Pet Travel Store.
