Specification: Color: Natural Material: Wood Dimension: 48" x 48" x 31" Weight: 45 lbs. Description: Expand your composting setup with this Add-On Kit designed to fit seamlessly with the 308 Gallon Cedar Wood Compost Bin. Ideal for turning your single bin into a more efficient, three-stage composting system, this kit makes it easy to rotate materials for faster breakdown and better composting results. Simply move partially broken-down material from the main bin into the add-on, and start fresh in the first bin again. For a full 3-bin system, order two add-on kits. The kit includes 2 posts, 21 interlocking cedar boards, and 36 spacers, and can be assembled easily using just a rubber mallet—no tools required. This add-on matches the size and style of the 308-gallon compost bin (sold separately). To protect your compost from the elements, use a tarp or plywood cover (not included). Great for backyard composting of garden and kitchen waste, this setup helps manage larger volumes efficiently.
