8300-02 Window Lock

A home owner from Illinois says:
Hi -

I am looking for the lock in my pictures. The holes are 2 1/16" on center and 11/16" from the window side of the latch. The numbers on the bottom are 8300-02 on the white piece and 8303 on the gray piece. There is also a 1 to the left and down from the 8303 on the gray piece.

The white latch is 1/4" thick around the screw holes and 7/16" on the thicker portion where the latch is.

It looks like a match is Product Code 90-278.

I hope that is enough information.

I agree, our 90-278 looks like a good match. The dimensions all seem to line up, as well. As long as the size is the same I think you should be good to go.

Curious for follow up. I need to replace the same lock submitted last year in this post. If you bought the 90-278, did it work?
