Searching for Anderson horizontal slide window latches

Hello there. I'm afraid we don't carry a sash lock with 2-1/8" hole spacing. Could you double-check? Be sure to measure from the center of each mounting hole. If it's 2-1/16", you might be able to use our 90-278, so long as the backset (or the distance from the center of the holes to the back edge of the lock body matches what is shown below). Please compare.
