vinyl window latch

We don't sell this exact lock, but we sell a ton that are similar in concept. The best match is ultimately going to depend on size.

With that in mind, can you give me a few dimensions? I'll need to know the distance between the two installation holes, center-to-center. that's probably the most important. The depth of the part will also help us find something that fits in the same space. Don't worry about total length, that's not really all that important as long as the screw hole spacing lines up.

Lastly, can you tell me how this secures in the frame? Is there a keeper or does it just slide under the glazing of the top sash?
