Really happy with this gate. It feels sturdy and well made, and the pressure mount made installation really quick without having to drill anything. The door swings smoothly and the width adjustment worked perfectly for my deck. It also looks much nicer than most pet gates I’ve seen.

-Sarah M

Yes, as long as the mounting points are flat and at least 1.38" wide — this includes most stair banisters and straight railings. It won't create a secure seal against round or curved railings.

It's extra wide and expandable, fitting openings from 28.5" to 61.5". The correct extension pieces are included automatically based on the size you order, so no separate purchase is needed.

This gate is designed specifically for pets, not children. It's not recommended for toddlers, since young kids can figure out how to open the pressure-mounted door too easily.

No — it's a pressure-mounted, no-drill design. The tension mount holds it securely in place without tools or permanent hardware, so it won't damage your railings or frames, and you can move it whenever you need to.

It's built for outdoor use, with a UV and weather-resistant powder coat finish that holds up in extreme weather. That said, it's versatile enough to use indoors too — anywhere you need a barrier.

Loved by Pet Parents Everywhere

I’m really impressed with how sturdy this gate feels. We installed it on our deck to keep our dogs from wandering off, and it fits securely without needing to drill anything. The swinging door is also really convenient when we need to walk through.

Ethan M., Denver, CO

This was exactly what I needed for the opening on my back porch. The pressure mount made installation really simple, and I didn’t have to put holes in anything. The metal feels heavy duty and my larger dog hasn’t been able to push it around.

Chloe B., Austin, TX

I bought this to block off part of our deck and it has worked great so far. It looks much nicer than the cheap plastic gates I’ve used before, and the black metal fits in really well with the outdoor space. The door swinging both ways is a nice touch too.

Very solid gate and surprisingly easy to install. I was worried my dog would be able to knock it over, but once it was tightened into place it felt extremely secure. I also like that I can take it down later without leaving holes in the deck.

Michael R., Mesa, AZ

This gate has been a huge help with our dogs. The spacing between the bars is nice for keeping them contained, and the height works well for both of our dogs. The walk-through door makes it much easier to get in and out without moving the entire gate.

Samantha L., Tampa, FL

Really happy with the quality of this gate. It feels much stronger than the lightweight gates we’ve had in the past, and installation only took a few minutes. We’re using it on our porch and it has stayed firmly in place even with our bigger dog leaning against it.
