CedarSafe Closets by Giles and Kendall offer ClosetLiner cedar closet planks in 100 percent natural Eastern red cedar. Cedar closet planks help repel pests such as roaches, silverfish and moths and resist mildew. The planks are easy to install, says the manufacturer, and require no finishing. Installation is a do-it-yourself project that requires a claw hammer, tri-square, saw and nails or adhesive. Planks come in 15-sq. ft. packages or the larger Pro Pak boxes. CedarSafe also sells cedar panels and moulding.
