ZRFCXE Window Locks,4 Pack Sliding Window Locks with Key for Vertical & Horizontal Sliding Windows Doors,Easv to Install,Adjustable Security Window Lock for Patio Bedroom Home and Office (Black)

I ordered this ZRFCXE Window Locks,4 Pack Sliding Window Locks with Key for Vertical & Horizontal Sliding Window to use on a large sliding glass window that needs to be left partially open. I recently installed a couple of amateur radio antennas and did not want to drill through stucco to bring the cables inside. Instead, I ran the cables through a pool noodle and use the pool noodle to seal the window. Obviously, the window needs to be left open to accommodate the width of the pool noodle. It was easy enough to relocate my alarm sensor, but I thought it would be foolish to rely on the alarm and not have a way to securely lock the window. I started at my local big box hardware store. First, I tried a simple thumbscrew equiped lock. It would not fasten down hard enough to prevent the window from opening. The, I tried a lock with a lever. Once again, it would not fasten down hard enough, and in the process of trying to get it tighter, the lock broke into 3 pieces. Honestly, I was not expecting much when I ordered these ZRFCXE locks. I was wrong. These locks work great. They screw down hard enough so that they can't be moved once tightened. The key provided does a great job at tightening the screws, and the small plastic insert really does keep the window frame rail from being damaged by the screws. I ended up using two locks -- one on the bottom rail and one on the top rail. I could not be happier with my purchase!

These work great! Fit perfectly and keeps the window from opening. Easy to install and looks great. We have the emergency exit window so I’m not worried about needing to get out. I’m more concerned with anyone trying to break into the trailer. I’m pretty confident that the window won’t be able to be opened from the outside. But if someone wanted to get in they cud just break the window, smh. They are metal and good quality. They are easy to remove with the tool but not without it. We were given multiple tools so we can place them several places so we will be able to find one if needed. We did leave one in the RV. I recommend these for anyone who wants to keep the window shut.

Excelente producto, resistente y facil de instalar.

Son seguros y dan buen aspecto al dejar de poner trozos de madera por seguridad.

Cost effective, easy to install and does what it needs to do. Extra keys are provided for added convenience and safety. Only downside would be a lack of a quick release in case of an emergency. This could prove detrimental if this product was blocking your only egress.
