I can't seem to find which window lock model these are. I can't find a serial number on the lock or window. Have tried a few replacments off amazon but nothing has fit. I'd rather replace the locks then get whole new windows. I would need about 20 of these locks

Hello there!

Thank you for reaching out to us. We carry a large handful of locks and keepers similar to what you have here so I'm not sure what to recommend exactly. Can you write out the distance between the two installation holes, measured from center to center? That would help me narrow down some options.

Sorry for the delayed response i just saw your most recent message.

For the larger piece, The installation holes are 2 and 1/16th inchs apart.

On the smaller base piece, it is 2 and 1/4 inches.

I also just noticed the windows were through a company called "truth" which is no longer around. See attached photo which has the serial number etc
