Up for sale are various sizes of lump stoppers. The lump stoppers work well with small, medium, and large style of sumps. The lump stoppers were professionally made and are very strong. The triangle design helps keep full grain flow while busting up any small chunks of grain that may be in your grain bin. Each lump stopper has an opening to slide right over the grain bin sweep. This design of lump stopper is the best that i have come across and is much safer then some of the homemade lump stoppers out there ( square style design with old cutting edge knives welded to them).
Prices vary from $225- $275 depending on size of lump stopper
