Window patch replacement

A quick learner from Houston says:
I am looking for a replacement . The distance between the 2 holes is either 2 inches or 2 1/16 inches (kind of hard to tell precisely since the top of latch curve). Thank you

Hello,

Depending on the back set of the installation holes in your lock, you could consider the 90-161 with 2-1/16" hole spacing with a 7/8" back set. We also offer the 90-278 with the same hole spacing but an 11/16" backset. Keep in mind that the front aligners on your old lock are not critical in the operation of the window lock but you will need to confirm that the installation holes are exactly 2-1/16" apart from center to center.
