Improved Childproof Door Lever Lock (4 Pack) Prevents Toddlers From Opening Doors. Easy One Hand Operation for Adults. Durable ABS with 3M Adhesive Backing. Simple Install, No Tools Needed (White, 4)

My toddlers kids cant figure it out. Perfect.

This one certainly keeps the toddler out of the room! But it’s annoying to lock compared to the kind that has the bottom piece which slips side to side. That one is easier to lock since it requires one hand. But this one definitely does it’s job so I’m definitely happy with it overall

Works great but they will take the paint off of your door

I had to make a slight modification, not thinking through the process appropriately. In the first picture, we had a sliding door with a side latch. So I just had to place it in a different position. In the second picture, the handle has to go up to engage the triple lock on our door. For this to work, I had to saw off the solid piece. Just wanted to show the versatility on these items in case anyone else was wondering how they may work for their doors. Good luck all!
