your part number 58-162

your 58-162 looks like it would fit my daughter's Pella storm door sweep. Hers is a v shape, 1/8" broad at the top, but is 4/8" in height. I think the 1/16" extra likely would not cause a problem but would like to know your opinion, thanks. I can find no identifying numbers on the door. The sweep is 36" wide.

Would you be able to adjust the bottom of the door so that it moves up a little? Many storm doors are able to do this. If not, then 1/16" of an inch is not that long, but it could cause the door to drag a little. However this does seem like the best choice based on your measurements.
