Muskingum Equipment Outfitters’ mortar/concrete tub, the Tuff Tubby, holds 10 cubic feet and is made of a durable, lightweight virgin polyetholene. The material is light in color to help repel heat, allowing the tub to stay cooler and requiring less tempering of material. The Tuff Tubby has a non-stick surface and rounded corners for easy clean up. The Tuff Tubby works on conventional and hydraulic scaffolding. Optional eight-inch wheels make for easy mobility on scaffolding and inside buildings.
