We found this Cardinal Pet Gate with the optional Extension a perfect choice.This gate system is very strong, coated to prevent rust from the elements, and the hinge system was easy to install. Plus the fact that this optional extension was available allowed us to have our staircase closed off. The Cardinal system has an adjustable main gate, which allows coverage over a nice range of openings. Our 4' opening was just a bit too big, thus we also purchased the extension, which bolts to the main gate making a nice solid gate. Make sure to purchase the stainless-steel screws so you can have rust free protection.One note, the locking mechanism seemed a bit weird when I first saw it, but once installed, it is great! We also use this as a baby gate and the locking mechanism can only be opened by pushing two outer taps at the same time that you lift the gate slightly...very difficult for a toddler...impossible for our cats! ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars works fine *by R***Y on Reviewed in the United States on April 25, 2024* Works fine. Bought three gates plus this extension and installed them outside on a deck. So far seems to hold up fine. The only complaint is the latch system. Too cumbersome to use. Can't open the gate without using both hands. and even then can be very awkward to open. I took the locking mechanism off and the gates work fine now with one hand. It still has the pins that hold the gate shut in place by sliding the gate up and dropping pins in the holes as designed. Personally don't see the need for the additional lock that I removed. Gate can not open without being slid up out of holes. It is mounted low enough to the deck so our dog can't get under it to push it up. Never has tried. Anyway, works for me. Seems to hold up to the weather in northern Minnesota fine so far. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Gate extension *by A***R on Reviewed in the United States on March 31, 2024* Now we can just let our dogs out the door, they can run out fenced in the back yard. Had to get because one dog ran in road and got hit by a car. She was lucky only had a broused back. She is better now. Thank God we have this gate now. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/9029011-bx1-10-5-in-baby-gate-extension-black](https://www.desertcart.us/products/9029011-bx1-10-5-in-baby-gate-extension-black) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-13*
