Crestline Casement window locks

Hello,

Thanks for posting! Your window lock reminds me of the 90-320 Wood Sash Lock. To determine if this is the correct replacement match carefully look over the dimensions on the website.

Unfortunately, we are not able to supply a replacement for the window. You'll need to reach out to either the manufacturer or a local window supplier to inquire about your options.

Apologies that we could not be of more help with this repair!
