Sliding Window Lock with Key, Security Window Locks for Up and Down Window Horizontal Sliding Window Safety, Child Proof Sliding Door Lock Bar Vertical Stopper Easy Installation (2, Silver, Standard)

Great product .. I replaced some smaller locks with these because they weren’t wide enough to clasp the window and glad it did these are slot stronger and thicker metal. Using o. Sliding 65 “ high windows , and they work

The lock worked exactly as it was supposed to work. Very easy to install and sturdy. Based on the reviews, I was unsure if the lock would work on my large sliding door. But the lock fits easily in the sliding door track. Once tightened, the door wouldn't move at all. I recommend them.

I love these they work perfectly. Easy to install

Didn’t fit in my sliding door, the edge on door frame is too thick and curved. However I was able to use it at windows, and it works well. It’s not something you want to open and close all the time, too much work, but definitely feels secure to have it on the windows more permanently. I set it so I can open windows, but only a little bit. You get a heck of a value in the box, 8 locks, and keys for each lock! I also wish they came in white, as my window frames are white. Why black only? Anyways, if you are lucky and they fit, they are great.

Easy to do and use,works wonderful and is sturdy!!! Used to secure and lock sliding patio doors.Thank you!!! Would recimmend.

The world is getting crazy scary, protect your home!

We love this product! We have a 4 year old that likes to go outside when she shouldn’t. We also have a sliding glass door that the only way to lock is with a piece of wood and a door latch. She can easily unlock and move the wood. This lock worked wonders! She can’t open it and it’s so discreet we always forget it there when we need to go outside. It definitely does the job it’s designed to do!

Purchase for 4 for the windows I wanted to have secured. Works exactly how I wanted and needed them to. Using to keys is easy and the design of the screws prevents little ones from accidentally loosing the window locks. 1 key per lock is great, I have the key located close to each window just in case of an emergency.

Excelente producto para seguridad
