Multi-point lock

Thanks for reaching out! We carry a few different lock mechanisms that could potentially work to replace your existing locks. Take a look at the 38-095, 38-096, 38-138, and 38-139. To determine which of one of them would be the best fit for your window, you'll need to carefully compare their dimension and designs. Their dimensions can be found on their respective pages on the website.

I would suggest starting with confirming the dimensions for the distance between the installation holes, from the center of the top hole to the center of the bottom hole. Both the 38-095 and 38-096 have the same installation hole spacing measurement and the 38-138 and 38-139 share the same measurement. Once you've narrowed down this measurement, that should make it easier to determine which of them is the best fit.
