Prime-Line U 9802 Extruded Aluminum Sliding Window Lock, 1/4 Inch, White, 2 Pack

Easy to use and does the job.

After building a coaxial cable window pass-through for ham radio cables the window had to be left 2" higher than the fully closed position. A pair of these locks keep the window secure. It is not a a living are of the house so I have no concerns about it taking longer than latches to open the window.

I'd been curious about this product for a long time, and decided to buy one, which was a surprise when I noticed it came in a packet with two. I have several sliding storm windows, which I like to open occasionally to let some fresh air in, but even though the area I live seems to be safe, I felt worried about leaving them open, as there's nothing stopping someone from removing the screens and lifting the windows up to get in. I wanted to buy a few of these, but am glad I ordered one set. I hadn't really thought about how and where they would need to be attached to the windows, until I had them in my hand. I first tried the bedroom window (which is different from the rest of the house). I pushed it into place where it seemed obvious to go, and then tightened the screw after determining how much distance I felt comfortable leaving the window open. I was pleased that it attached perfectly, it was so easy, I wished I'd bought them years ago. Next I tried all the other windows, but unfortunately I couldn't get one to fit. The window in the bedroom, slides sideways, the others slide up the way. In the bedroom the part where the lock attaches, is very narrow, just 1/4", the other windows over 3/8", or 1 cm.to be precise, Unfortunately there's no way these will fit your windows, if the area it needs to slide over, is more than 1/4". I'm happy at least it will fit one window and was worth the money.

I used this for my aluminum window, so that I can have the window open, and not be afraid that someone will accidentally fall out. It does the job. I just don't like that the screw side scratches my window. I had to place a small cardboard piece between the window and the window lock. It kinda looks tacky, and is annoying to have to adjust each time I want to move it.

These pieces are so simple to use. Attach them to your window frame so the window can be partially open without concerns of someone gaining access through the window. You can rest in peace at night or when you are away. One word of caution, the pressure screw has a pointed end. That’s not a problem with a metal framed window, but the vinyl framed windows, caution needs to be used so the vinyl is not pierced with that pointed end.

on the picture it shows open straight channel ,but the on I received its on inward angle ,which makes it hard to install on single hung window

Great price for secure window locks! Easy to install, strong, great peace of mind for extra security.

I purchased them to prevent someone for entering my home. I can open my window enough to let air flow. Not enough room for someone to get inside.

Works great for securing your windows. I use this to secure my window after I install my air conditioner. As my window is on my balcony I want to make sure that when I am not at home my window is securely locked.

Excelente producto.... Nota... Hay que utilizar una buena pinza para que quede bien sujeto, obviamente marcara el marco, pero es un muy buen producto!

Ótimo para fechar janelas e portas de correr de vidro (blindex). Uso sempre que vou viajar.

Produto simples mas muito legal. Trava a janela em várias posições. Como minha trava da janela quebrou, essas mantém seguro e posso deixar uma pequena fresta para entrada de ar. O gato já foi testar e não conseguiu abrir. Aprovado!
