Alcan sweep or sash lock
Thanks for your post! I'm confident we can supply a replacement for this lock but I'll need to see a photo of the keeper to narrow down the correct replacement match. We have a sweep that matches your specifications but I am wary it may not be compatible with the existing sweep given the different in the design.
Please let me know if you have any additional questions!
Thanks again!
Thanks for the additional photos. I believe our 90-180 Window Sash Lock should work as a replacement. It has the same installation hole spacing as your existing locks.
Your existing keeper might not be compatible, so you may also need the 90-183 Sash Lock Keeper.
Carefully double check both of their specifications to ensure this will work for your repairs!
