Toddleroo by North States Sliding Window & Door Wedge Locks | Limits The Space That Windows and Sliding Doors can Open | No Tools Required | Baby proofing with Confidence (4-Pack, White)

Used to prevent windows from being slid up too far.

It was very hard to peel the backings off of these took forever.Not all that impressed with the item.

I’m disappointed to be honest. My 3 year old knows how to open the downstairs windows and escape. This took him all of 30 seconds to knock off. Now we just have to leave him in his cage so he doesn’t escape. Kidding! Product isn’t that great though

It wouldn’t fit on the window I could push the window up over it but it worked in the well u can see in the picture not sure what it’s called. I just put it on hopefully it stay stuck and my son doesn’t realize that it’s Velcro and come off. He’s five.

When I bought these locks, I wasn't sure how well they would work and if the Velcro would be strong enough from keeping someone from breaking in/ opening the window more if the window was open a bit. Well, I unintentionally got to test that. I had my sliding window open a bit and wanted to open it more as it was a beautiful day. Eager to get more air into the house, I pushed that window up and .... got it slammed because I forgot about the safety/ wedge locks. Holy cow! They work!!! That window was not going up, no way. It also wasn't going down for a minute, but that's my fault. So, anyway, long story short,- I feel totally comfortable sleeping with my window a crack open because I completely trust these locks. So whether you are worried about your toddler climbing out or someone coming in through the window, these locks are a super easy, inexpensive solution. Just remember to remove the wedge if you ever want to open that window all the way....
