Need a replacement sash lock
We may have a suitable replacement lock for this. Before I can recommend anything, can you kindly tell me the distance between the two installation holes, center-to-center?
I'm sorry to say that we don't sell either locks or keepers with a 2-1/8" hole spacing. Your response did say this was an approximate measurement, though. I think it would be best if you were as precise as possible, given that we don't sell this size. Make sure to only measure from the center of each hole, not their edges.
If you're confident that 2-1/8" is the actual measurement, then this is not a size we can offer at this time. I apologize for the inconvenience.
