about window lock

We carry one sash lock with 2-1/4" hole spacing, our 90-274. I doubt this is what you need based on the design. Double-check your hole spacing; be sure to measure from the center of each mounting hole. See our 90-161 or 90-077C, which have 2-1/16" hole spacing. Compare with your old sash lock and see if you think one of these match what you need.
