I recently had the pleasure of installing the SmarketBuy Aluminium Extra Large Dog Door, and I must say, it’s been a game-changer for my furry friend and me!

Firstly, let’s talk about size. This door is enormous, with a frame size of 17.5" (W) x 27.7" (H). It’s perfect for pets up to 220 pounds and can fit doors or walls over 1.25" thick, making it incredibly versatile.

The flap opening measures 14.4" (W) x 24.5" (H), providing ample space for my dog to move in and out comfortably. The cutout size in the door/wall is 14.6" (W) x 25" (H).

Installation was a breeze, thanks to the included cutting template, instruction guide, and mounting hardware. The process was straightforward, and I had it up and running in no time.

What I love most about this dog door is its ingenious details. The durable aluminum slide-in panel, security sliding lock design, and weatherproof magnetic closure ensure my home stays secure at night or when I’m away. The two UV-resistant flaps are also a plus, as they offer energy efficiency and suit different climates.

Overall, this pet door has made life easier for both me and my dog. It allows him to go out independently, giving us both more freedom. I highly recommend the SmarketBuy Aluminium Extra Large Dog Door to any pet owner looking for a reliable, easy-to-install, and versatile solution.
