  • Buy Small

    We would like you to consider buying from our website instead of from other large national retail sites; where we also sell.

    • We are a small family run business and do all order fulfillment from our own modest basement warehouse regardless of where you purchase.
    • We use the same national name payment processors and offer identical return and exchange services.
    • When you purchase from us you will not pay state sales tax unless you live in MN where we are located.

    Anyone familiar with small businesses will tell you; after customer service, cost management is a top priority. avoiding the other guys listing fees makes a huge difference for us.

    • A logical question is why don't you just charge less on your website? The big guys make us match the lowest list price, so a price change here means a price change everywhere, unfortunately that does not change the listing fees they get paid.

Really cool

It’s a very well thought out product. Works really well. I will be purchasing additional ones in the future.

My door was hollow core, which causes some “flopping” in the end result. I added additional wooden spacers inside the door to make the door more rigid and give the hinge something to attach to in the middle.

Even with that modification, there is still enough flex in the hinge to cause the door flap to wobble around even when locked close. The inclusion of additional screws (10 instead of six) would be helpful, since the flex is greatest at the spots where the hinge is not attached to the door.

If I were able to purchase a reinforcement kit containing additional screws and some wooden spacers for hollow core doors, I would definitely do that for future installs.

It would work well if my door wasn't hollow

There is only one place on the corner of the door that has wood, the rest is hollow or crossed with cardboard.

Dear Customer,
If you are interested we have a short video that shows how it is posible to reinforce doors that have less interior framing.

Best,

If you can modify Ikea furniture this is easy. I read and watched instructions fully first. Than before each step I reread. I came across two problems. I laid out and cut ON the line, I should have made the corner bigger. This caused the metal hinge to be sticking out just a mm on the bottom. But my door gap made it a non issue. While trying to lock it in the open position after installation it wouldn't lock. Reread the instructions! I noticed my gap was not consistent, fixed that. To finally get it locked open I gave it a firm push down like suggested. It worked! The biggest change I would make if installing again would be to test it in BOTH locked positions before installing. Would have saved me some irritation.

Something special!

It was fast getting to me, easy to install, easy to use, and best of all the fuzzies love it! What else can I say? The included template made the installation super easy, and it's easy enough for my parents to use! It is the best money I've spent in a long time!

Perfect!

I'm not the handiest person, and my circular saw is cheap and small, but installation was still very doable- took about 30 mins. The hinge is not super heavy duty, which is fine for our home, but if you have rambunctious toddlers or something it could be an issue. Overall a great solution to maintain privacy!

Excellent product

I installed this product on two of my interior doors - excellent product. Easy to install… instructions were accurate! Our cat started using them immediately without hesitation. Very good experience!

I love it and so does my cat!

I feel the kit is expensive for what it is, but it works great! This is the second one I bought as my original one was damaged and stopped opening probably

Good- cat size?

It is easy to use. The only problem seems to be that my cat might at out grow it, as she is a medium to large breed. So for larger cats you might consider moving it further up then instructed (if possible).

Love it!

As easy and perfect as I hoped!

The instructions were very clear and easy, all the parts were there, and the whole setup took less than an hour! Very, very pleased. Be aware, your kitties may avoid it for the first few hours, because the door they're familiar with will suddenly smell like sawdust lol. My kitties got used to it and started using it after an hour or so.

Kitty Corner - Does the trick.

So I actually bought two of these, one for the bedroom and one for the laundry room where kitty's potty is. After cutting the door and installing the bracket, I had a couple thoughts... 1) the corner being cut off is a really good look and I prefer it better than the 'mouse hole' look of some other designs. 2) immediately after installation, I asked myself why I bought this thing and didn't just cut off the corner (free), but just a day later I had a reason to lock the kitty in the bedroom, so I was happy that I could flip the door down. That being said, there's still a very obvious gap at the cut, so I wouldn't want to leave it down, as it's not a great look, but it serves the purpose of blocking the passage. Overall, 5 stars for shipping, design, functionality, instructions, and quality. I'm very happy I purchased it for the bedroom, but I wish they sold a different type of "cap" that would cover the cut corner for the door that would never need to be blocked.
