Latch replacement

Hey there. Can you tell us the hole spacing, or the distance between the center of each mounting hole? That will help narrow down your options. Thanks.

Thanks for getting back to me. See the backset of the 90-077C below. It is 7/16". If that matches your old sash lock, this might work as a replacement.

Note that your old lock appears to be riveted in. You will need to carefully drill those rivets out to remove it.

Personally I am not sure this would matter, but if you want something that has the same profile, see the 90-077A. One issue here though is this replacement has alignment nubs on the back edge. So you'd need a new keeper also. See the 90-177.
