Need to replace lever hardware on Cole-Sewell Storm Door
Start by looking at our 40-049. Carefully go over the dimensions and let me know if you think this could work for you.
Take a look at the diagram of the 40-049. Compare your measurements the same way we have in the photos to determine whether or not this will work for you.
Hey there, maybe I can help. The measurements of our 40-049 do seem to be close to the ones you need. As for the screws in the photo of the mortise latch, the two holes at the top and bottom edge hold the lock into the door frame. Concerning the other screw at the top, that holds the face plate to the mortise latch (I believe now the face plate is riveted on). The other screw at the bottom holds the key cylinder in place. Take a look at the related video to see how to install.
Cole Sewell isn't in business anymore, unfortunately. I don't think an exact match for your old handle will be available anywhere. I cannot guarantee that our 40-049 can work, but I really do think it's our best option.
