Safety Innovations Complete Deluxe Bi-fold Door Lock - (2- Pack) - Fits Bi-Fold Doors from 1 1/8 - 1 3/8 Thick - Made from Unbreakable Clear Polycarbonate

Cant believe how long it took me to discover these. I was taping doors shut to prevent my too-smart cat from letting herself inside to chew all my shoelaces. This is such a simple and elegant solution. Wish I discovered these years ago!! Fit perfectly with my bifold doors.

I love the use of these. They do the job but I will say they did peel my paint on the closet door.

Such a great cheap way to babyproof folding doors.

I tried them and had a hard time getting them to work on my doors. partly because the insert to help it hold the thickness of my door wasnt easy to use/adjust. also, I am short so its hard to slide it back and forth for me.

Love this little gadget! Our toddler always opens the pantry doors - this works perfectly! Stops him from opening the doors and it’s easy to slide over when we need to open it ourselves.

My 3 year old kept pushing her closet doors shut and pinching her fingers. These clever things have solved that problem and eliminated tears (or at least tears from pinched fingers)

Hiding all my presents in this closet now!!!! Kids can’t get in.

This safety device to keep bifold doors closed is amazing! Our bifold doors are on our laundry room and at the top of our steep basement stairs. My 18 month old grandson wants to get into everything. These really work!

Clear plastic is not noticeable: definitely strong enough to deter cats from opening bi fold doors (dog doesnt try)

This is the best thing for bi-fold closets! My 2yr old son was CONSTANTLY going in his closet at nap time and taking everything out or he’d pinch his fingers. This solves both issues!!! It even comes with a little attachment piece if your doors are smaller you can put it on and have it work the same as standard doors!
