It's easy to install and customize your wood rack with two vertical bars, 12 horizontal bars and 6 spacers (plus screws). Your wood rack can be installed on drywall studs, masonry wall, steel wall or shed, or wood fence. The horizontal bars have a 12-1/4" shelf depth providing plenty of storage space for your wood (or other items). The vertical bars are 41" high. The bars are made from high quality, powder coated tubular steel and provide six levels of storage with a 110-pound capacity per level. The recommended distance to support the designed weight capacity is 4' to 6' wide. For longer or heavier material, use multiple wood racks. Imported.
