This set of four (4) heavy-duty steel corner brackets lets you build 2 x 4 storage racks, shelves and worktops in any convenient size. Stack N Store's design keeps your valuable firewood up to 5" above ground level - safe from harmful ground moisture, pests, and decay. The raised design also permits faster drying of green wood for better and safer burning. Select the 2 x 4 lumber of the right length, and add the brackets - you're done...it's that easy! Add screws or nails in the pre-drilled bracket holes for added stability. Stack-N-Store brackets are virtually indestructible.
