Simple and Secure
Size: 8 Pack
Color: Black
I purchased these window locks for my sliding windows to add an extra layer of security. Installation was very simple and only took a few minutes per window. I appreciated that the necessary tools were included, which made the process quick and straightforward. The locks themselves feel solid and well-made. Once tightened, they fit snugly on the window rail and don’t shift around. I also like that they require a key to loosen, which adds another level of security compared to basic clamp-style locks. Overall, these provide real peace of mind and seem like a durable, effective security upgrade. I’m very happy with this purchase.

Perfect for security in my opinion
Size: 4 Pack
Color: Black
These are great! Easy to install, can adjust to any opening size, stays in place! I want to open windows without the worry someone will try to come in, or my cat will try to push the window open. Feels secure, not too bulky and easy to move to different window or sliding door as needed!

Great product
Size: 4 Pack
Color: Black
These work so well. Buy it now. My kids have tried to take them off and they can’t. I’m also confident no one could pop them off even if they broke the glass from the outside to try. They’re not budging without the key.

Revisar las medidas del riel - Check the rail measurements -
Size: 4 Pack
Color: Black
Es muy útil, lástima que no tuve en cuenta la medida del riel de mi puerta de balcón, pues no le sirvieron. las use para bloquear unas ventanas y fueron perfectas, recomendación, revisar bien las medidas de los rieles - It’s very useful; it’s a shame I didn't check the size of my balcony door track, as they didn't fit. I used them to secure some windows instead, and they worked perfectly. My recommendation: double-check the track measurements.

Simple Upgrade That Makes My Home Feel More Secure and Comfortable
Size: 8 Pack
Color: Silver
I’m really happy with the ZRFCXE Window Locks, 8 Pack Sliding Window Locks with Key. They were easy to install and immediately made my windows feel more secure and stable. It’s a simple upgrade, but it really adds peace of mind knowing the windows are properly locked and reinforced. What I didn’t expect is how helpful they are for windows with a bad track or ones that don’t properly lock into place when partially opened. These locks actually let you prop the window open safely and keep it in position, which has been a game changer for airflow throughout my apartment without worrying about the window sliding or shifting. The locks feel sturdy, and having the key feature adds an extra layer of control. Overall, this was a practical and reassuring purchase that makes my space feel both safer and more comfortable to live in day-to-day.

Simple, easy, safe what more could you ask for?
Size: 4 Pack
Color: Black
I bought these to lock the windows in my home especially in the summer when I have fans in the windows. I want these windows securely sealed on the fans and endurance someone isn’t going to be able to get the windows open and this definitely does the trick. The nice thing about this is that it’s easy to install and un-install so end of summer will be easy to remove fans and then I can secure the windows for winter ensuring that nobody gets in through them. Took less than 2 minutes to install all 4 locks on 4 separate windows. Easy to install. Simple to use. Good material. Items as described in add. Highly recommend if you’re looking for something simple to secure your home.
