Latch for Thermal industries window
Thanks for reaching out to us. We may be able to help with this. However, we don't sell a lock with 1-15/16" hole center spacing. Are you measuring from the center of each hole? If not, can you write out the distance between the two installation holes, measured from center to center, for the lock and keeper? That should help us narrow down some options.
I'm sorry to say that we don't sell a sash lock with 1-15/16" installation hole center spacing. You may want to double-check to be safe.
The 90-284 and 90-183 keepers measure 2-1/4" on the installation hole centers though. Review the specifications and see how they compare with yours.
