Lacey Harmer Hoppers are a great addition to our EFR and EFM Filters.  They are available in 10 different models ranging in size from a 1/2 yard to 10 yards.  With the easy tripping mechanism in the front, they are the only self-dumping hopper on the market to date.  The added lid manufactured by Honeyville gives you an enclosed dumpster that can be added to a system to replace an existing dumpster or barrels.
