Do the online calculator - makes sizing a breeze especially for how many extensions you need!

"I needed two of these to add to my dog door and it was so easy to install onto the door to extend to the height that i needed for the height of my door frame, the calculator thingy on the website is perfect and spot on in recommending the items you need in order to fill your entryway properly for the door to fit correctly. t was actually a breeze to figure out and then add to cart. The instructions are simple and install a breeze! If you are unsure as to what you need, the right size for your pet etc - do the online calculator - it does ALL the work for you and the process so simple!"

Easy and convenient dog door.

"This door is amazing, we needed two extenders and all of it was easy to put together in the end. We are kicking ourselves for waiting this long to get it, the dog took a bit to get used to the flap but is great now. Customer service was amazing, highly recommended. Also looks great."
