Customer Reviews for Prime-Line 3 in., Extruded Aluminum, White Reversible Sliding Window Bar Lock

Reversible sliding window bar lock was an excellent choice for securing my windows & sliding door.

Just what I wanted and will purchase a few more.

It works. However, it fit better on some sliding windows in the home, Not quite sure why that was the case.

Exactly what I needed. Thanks.

These are awesome window locks. The extension bar keeps unwanted visitors from removing the window when it is open

Did not work on my windows

The lock is great and secure and very easy to install and shipping was fast. I recommend this product for any sliding windows.

Does it's job. Prevents window from being removed when installed properly.

Ordered these for vinyl sliding windows, which this said it was for along with sliding doors. Had to return them as they did not even come close to fitting our vinyl windows. Disappointed.

It's much smaller than it looks in the picture. Also, it's difficult to tighten the thumb screw so it doesn't move easily when the window is opened. You are better off with cutting a wooden dowel, about 5/8" in diameter, to the desired length(s).

It works very good i will order some more. Very good tool.

The device seems sturdy. It grips the track without any difficulty. Would it withstand a determined intruder's efforts? That remains to be seen.

East to install, plus gives added peace of mind having window security.

They said that it would be a couple of weeks before I got these and I had them in three days. The packaging was good. The pictures do not do this product justice. They are very solid and sturdy. The rod looked longer in the pic, so it was a nice surprise to see that it was shorter and you can also adjust the length of it. If you have the thumb screw facing the window it will not scratch it. Another selling point is that it can be used for right or left horizontal or vertical sliding windows. I have the new white eco windows and the white of the lock blends in wonderfully! I would recommend these to anyone. Also had my husband try and break in and guess what. He had to sweet talk his way back in!!

As sliding windows may be different in every country, i bought these as a "trial" experiment. Turns out, it does work pretty well and i m from Singapore. Its a matter of figuring how you want to attach it, be in top or bottom, left or right sided. More importantly, it holds up very securely and sturdy. The downside is that, the clamps will scratch your windows, and it would be best if you can improvise by adding a rubber grip or something to avoid abrasion. All in all, a very affordable and convenient piece of hardware to have at home.

Right sliders work better than left sliders, but works overall.
