I need 3 sash locks 3 inches long with the attached form factor. I am not sure of the Window manufacturer but I think it is Mayfair. All manufacturer information from the windows is lost due to Hurricane Katrina damage.

I'm not sure if we have an exact match for this lock, but see our 90-034 or 90-182 to start. Look over their dimensions and see if you could use one of these as a replacement.
