sash lock and stop

Hello!

The keeper resembles the 90-257. I wonder if this face mount keeper could be what you're searching for. Take a look at the specifications and see what you think.

We'll need more information to see if we have a match for the lock. Can you write out the distance between the two installation holes, measured from center to center? Can we also see a photo of the lock from the top? I can't make out the style too well from the underside of the lock.

I'm afraid we don't sell a lock in this style with that kind of hole center spacing. The 90-278 resembles what you have here in terms of design but the installation hole center spacing is 2-1/16" with an 11/16" backset. You may want to double-check your measurement just in case.
