Phillips windows hardware

I'm not sure what measurement you may be referring to. Are you measuring the full width of the lock, or just the hole spacing? Typically, the only measurement you have to be concerned with is the distance between the two installation holes, center to center, and their position relative to the back edge of the lock housing. The overall width isn't really important.

I would double check those dimensions to be safe. According to our records, customers with Phillips windows have used our 90-274 lock, which has a 2-1/4" hole spacing. The keeper that it comes with won't be the same as yours, but you can always reuse the original.
