I talked to 2 Dadant Branches and their main office. They do not sell the small cell wire crimped foundation in Medium size!! I think the confusion comes from the fact that they call "DEEP" foundation..."medium" and they call "MEDIUM" foundation..."super size"
The stuff they list in their catalogue as "medium" is indeed, 8 1/2 tall!
Bummer, I guess I'll have to dust off that spool of wire!
