Hello, Start by taking a look at the 91-004 and 91-005 storm window corner latches. This is a newer version of the ones that you show in your photos. These newer latches have a corner that just snaps in place. No need to use a screw or pin the corner place. Also take a look at the related top tilt corners. Let us know if you have any additional questions! |
