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!!

    Perfect - just what was needed

    Super Fast shipping all the way from the opposite coast, customer service was also quick on email. Height extenders fit easily on the 700 level and was the only way this shepherd could fly.

    Fit perfectly. No instructions and the two photos had the hardware installed differently on each crate. I thought the nut portion should go on top to make it easier to see if they were spinning loose. Maybe should have had washers for top and bottom.

    Quick Delivery! Great product and perfect for our Alaskan Malamute!

    Posted by Holly on 15th Apr 2019

    We are a military family stationed in South Korea. We ordered the giant kennel extension for our newly rescued Alaskan malamute. We were so weary about ordering online and having them ship to APO since this can range from weeks to months to get here. However, we received our kennel extender in about a week!! It is of great quality and we are so pleased with the product and the company. We will continue to order from this company in the future. Thank you PetTravelStore!

    Exactly what I needed

    Posted by Vanessa on 10th Apr 2019

    So grateful that this company ships to APO addresses!! Although my dog is less than 60lbs, his long legs and erect ears required that his GIANT Sky Kennel have 3 more inches of clearance above the top of his ears to fly. The extension kit was exactly what we needed and came earlier than expected.

    Thank you for this great product!

    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.
