This 3-bin design is compact and makes very efficient use of materials. As a builder, I love the fact that the frame requires little “extraneous” hardware and is extremely solid. If a composter could ever have that new car door “thunk” that says “well-built,” this is the one. Each bin has a side door for easy transfer and removal compost. Of course, you can also transfer over the top.
- FSC-certified rough-cut redwood
- .5 inch square galvanized steel wire cloth sides
- Optional screen table for filtering compost
