My solution to keep my pet downstairs

We opted for the Summer Infant Secure Space Extra-Wide Safety Gate, which is specifically designed for various installation types including stairs. Additionally, we used a Y spindle rod (8 mm) in place of the rods that came with the gate, to securely attach the gate to the bannister. This combination allowed us to effectively safeguard our pets while seamlessly integrating the gate with the unique structure of our staircase.

We only needed to use one of the Y spindle rods that came in the 2-pack, as the lower rod that came with the gate was able to hit the wider part of our bannister.

Installation experience

Installation was a breeze and probably took less than 30 minutes. The gate came with 3 different extension gates so that you could fit the gate to the width of your stairs.

This gate can support stairs from 28.5 inches to 52 inches wide. The width of my stairs was about 48″ at the bottom by the step. The width at the top was slightly wider due to the bannister tapering off.

I was able to use the pressure rods with the flat circle feet to press against the wall side at both the top and bottom. On the bannister side I was able to use the pressure rod that came with the gate only on the bottom and used the Y spindle rod for the top to attach to the bannister. This gate installs without any need to drill or use screws which was a key feature I was looking for.


After three months of having the gate installed on our curved stairs, we can confidently say that it has been a resounding success in keeping our pet safe. This gate has surpassed our expectations and proven to be highly effective in preventing our pet from accessing the stairs. Not only does this work to keep our young dog from going upstairs it would also work well for keeping your baby or small child from also from trying to climb the stairs. We are thrilled with how well this gate has worked, and we wholeheartedly recommend it to others seeking a reliable solution to protect their pets from stair-related hazards. I highly recommend this solution for installing a gate on curved stairs, especially if you have a bannister.
