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

This is the best! My toddler loves to open his closet doors and this was the perfect solution to prevent that! Highly recommend!!!

Title says it all. They are simple but work amazingly

I wish I had known these existed way before now!!! My toddler has figured out every single lock we have in the house. She would go into her room and change clothes constantly. I put these locks on her closet folding doors and she cant open them anymore. I dont have to deal with her constantly changing clothes, picking up clothes all over the house, and the unnecessary big piles of laundry anymore!!!

Very simple and effective keeping toddlers out where they do t need to be. Buy it you’ll like it

Pretty cut and dry, kiddos cant get in but us. Solid product

This was very confusing when I received 2 (instead of one) products AND included pieces that were not shown in item pics so I was baffled how they are used. Some instructions would have been nice....at least a picture showing what was included and generally how they are used. Worked well enough though...

We moved into a new house and I was storing the dog food in a closet with bi-fold doors. One of our dogs, who will remain anonymous, figured out how to bump the doors open, pull out the dog food container, open the container, and enjoy. These work great! Simple design. Easy to install on the doors. Easy to move back and forth to lock/unlock. Hardest part is remembering to lock when leaving!

We watch our 2 year old granddaughter who insists on opening our bi-fold doors into her treasure chest of toys. This simple device is perfect!!

I have 3 sets of bi-fold doors in multiple rooms in my house. I also have 2 mischievous Siamese kittens who were constantly opening them and pulling out the contents. These locks are very easy to install, and work perfectly to keep them out. The also blend in so well that you can hardly see them. I love them!

Finding a lock for bi-fold doors is all but impossible. I found this and decided to give it a try. While this is not exactly a lock, it does the job of holding the doors closed. The installation is simple...just open the door a bit and drop it over the top of one of the doors. (There is no drilling or tools necessary.) To close the door, use the drop-down handle to slide it to the center. This will keep the doors from opening. When you want to pass through, just slide it over either door and the door can then operate as usual. We use it to keep a pet out of certain areas of the house. It is made of clear acrylic plastic and does not stand out. The only thing I found was there is only a handle on one side. So, to lock/unlock from the other side you must reach up and slide the actual lock back and forth. This is not really a problem, however it could be improved by putting a dropdown handle on both sides of the unit. They come two to a package so I just installed the second one with the handle on the other side. Mine slides easy and is not inconvenient.
