For some Viking windows, customers have often used the 90-278 lock with a screw hole distance of 2-1/16"; however, others have needed the 90-274 instead, which has 2-1/4" hole spacing. It is hard to read the dimensions on the photo of yours, so compare both with your old hardware to determine what you need. We believe you can use the 90-301 keeper. |
