Security for your family
STERGDE brand window locks are made of high quality aluminium alloy, durable and non-deformable, providing the perfect extra security for your homes, flats, rental rooms and hotels. The window locks can be used on vertical or horizontal sliding windows, effectively preventing children and pets from getting lost and falling, preventing the window from being opened from the outside by intruders, and they can also be locked precisely in the draughty position, providing additional security for your family.
Easy to install and use
Place the lock on one of the tracks of the sliding window, put the anti-scratch protection spacer on one side of the screws, and then just tighten it with a hex key or vertical key, effectively locking the window in the exact position you want.
Sturdy and durable window lock
Made of high quality aluminium alloy, the surface is polished with high strength, not easy to scratch, rust, corrosion, oxidation, rust, even in the rain or water.
Very useful when opening for ventilation
When ventilating, you lock the window in the precise position to prevent the window from continuing to open, thus breathing fresh air, but also to ensure security.
Whether you want to keep kids and pets from getting lost or keep intruders out, security window locks give you peace of mind.

Just put these on all my windows after being broken into thru a window. They fit very snug and tight. Nice because I can open a bit to let air in but know the window is still locked.So glad to find these locks! Easy to put on, take off. Do not mar the window frame. Totally recommend!!

They did not fit like the picture. The screw barely grabbed onto the sill because the locks sit higher then the picture shows on my sill track. The plastic screw protector falls out as you put the device in place. However, the device does work!

There are a bunch of similarly-priced, though somewhat cheaper, options available for window locks. I ultimately chose this one for a couple of reasons:---More likely to be USA-made (based on the description not being your typical gibberish by a non-native English speaker or translation app---Superior build quality (based on reviews)---More flexible use and adjustability (based on reviews)I have not been disappointed thus far.We have 30 year-old windows in an 80-year-old house. Not one of them locks anymore. Installing these locks was quick and painless, and the fit is as good as one could reasonably hope. Attempting to open the window with maximum force (I'm a 33 year old male in decent physical shape) they don't budge at all, and they certainly feel rock solid. No complaints.

I ordered two sets of these total of 12 and all I installed them today. Myself only had one window left yet to go. It was hard to get to haven’t been able to get to it yet, but I am very pleased with these. I feel secure now, especially in one room. I was kind of concerned, but now that I have them fixed I’m no longer worried. I’m really glad that I found these on here. They are perfect sturdy and easy to install. I highly recommend these for anyone That is in doubt about security now I need to get my doors secured.

My windows slide horizontally and the window locks slide on very easily. The "key" isn't the best tool for tightening the locks in place, but the other provided tool works great. If you have an Allen wrench of the proper size, that would work well, too.I would say that for maximum security on windows like mine, the window should not be allowed to slide open at all. This will keep the window from being lifted out of the frame.For keeping toddlers inside and allowing some ventilation, allow the window to open an inch or two.
