Side panels in solid aromatic red cedar. A panel supports the open end of a hanging kit, shelf, or closet rod kit where there is no wall. These are the vertical supports found on the cubby units. Panels arrive in two 42 inch sections that join to make an 84 inch panel. This is our 12.5 inch depth, for narrow closets. If you are building around our standard 14.5 inch system, select the 14.5 inch version instead. The two depths are not compatible and do not connect to each other. Parts shown in gray in the images are for reference only. They show how this unit connects to a neighboring unit and are sold separately. Made in the USA. Milled in Kentucky from locally sourced aromatic red cedar. Please note that we upgraded our panel style to improve production efficiency. As a result, you may notice slight variations in the panels shown across our customer review images. The product images featured above accurately reflect the current design you will receive.
