What size flap does this come with the 5,6 or 7 inch?

5" Tall x 7" wide at bottom triangle. Pete - Goten Builders Farmtech

will this work on a wheat flour silo?

I don't know, we use them for bulk inshell peanuts and they work great. Honestly, I don't see why they wouldn't work, I'm just not should how wheat flour flows. It is just a flapper inside the tank and as peanuts pile up, they press against the flapper. It a not 100%, but close.

Very comfortable and a great addition to any mattress

Smell is a little overwhelming the first day. Very comfortable and a great addition to any mattress. I purchased for my camper, turned the firm memory foam mattress into a soft supportive bed.
