What’s the biggest storm drain anyone has run into in a parking lot (or anywhere)? I just got a 54 inch drain protector and I think the biggest drain I remember ever seeing was 3‘ x 3‘. This material is easy to cut and I would like to make one large piece for the biggest drain I may come across and then make one other smaller piece for a second drain. It’s pricey stuff so I don’t want to make it too small and find a drain that I can’t cover.
