On the video, you say to position the locks 3.5 inches above the bottom window. This may be a stupid question, but I want my windows to be able to have an opening of about six inches for ventilation so is it fine to install the locks higher? Or does the product prevent that in some way? Maybe the vinyl windows aren't strong enough? It looks like my neighbor the contractor should be able to install these easily.
From what I can see, this is the only product for windows that don't have vent locks included in the existing windows, right? So I can put these on my existing windows? What is your return policy if I try them on one window and don't like how they work? I will probably buy them for at least 7 windows.
I also forgot to ask if it is adjustable to a variety of windows, because I noticed that some other companies' products have to be ordered in different sizes depending upon the distance from the face of the frame to the face of the sash?
The product also allows for the windows to be opened up completely if needed, correct?
I keep thinking of additional questions. And I have one more. The locks aren't for kids but I want to use them for ventilation at night, so I need to know if they are strong enough for security purposes when they are locked in the venilation position. I came a across a competitor on Amazon and it got horrible reviews -- in that they were very easy to break. So I wanted to know if yours are strong. Thank you.
Sincerely,
Liz

Hey, Liz. The 26-387 is recommended to be set to 3-1/2" by the ASTM F2090-2008 & 2010 code. There is nothing physically preventing you from setting it at another height, but it is not advised.
These can fit on most windows, actually. As long as the frame is flat and not a peculiar shape. If they don't work, though, you can check out our Return Policy by visiting this link.
Yes, the 26-387 kit comes with a set of shims that allow you to set it at varying depths. You can see the video below for more detail.
