white window closure

Hello there!

We may be able to help depending on your dimensions. Can you write out the distance between the two installation holes, measured from center to center? Can you also write out the backset? That is measured from the center of the installation hole to the edge of the lock. 

I'm afraid we don't sell a lock with that kind of hole center spacing. Can you double check that for us to be safe? Can you also measure the backset as shown below and tell us what you find?

Great, thank you! The specifications you gave appear to match the 90-278 lock. Take a look at the specifications and see what you think.
