Sash lock and keeper

Question

Hello , I thought lock 90-180 and keeper 90-183 were the correct replacements but now I'm not sure . I'm concerned mostly of the center to center hole dimensions of each part . I work at a hotel and have over 122 windows and quite a few of them have broken locks . Thanks

Thanks for reaching out! The backset on the 90-180 appears to be a bit too shallow to replace your existing sweep lock. I believe the 90-278 would be a much better fit although, you'll need to be sure to double check the dimensions from the diagram below. This sweep lock comes with a compatible keeper. See what you think.
