This modular panel is designed for the horse owner who likes the look of wood in their stalls. Simply cut your own wood (up to 3/4" thick) and secure it into the channels with screws. Each panel measures 4 ft. x 4 ft. and weighs only 22 lbs. Each panel sits 3/4" off the ground for easy cleaning. The frame is made of 1" square tubing with 1" angle iron channels for superior strength and durability. The grills measure 15" high, made of solid 5/16" steel rods set 3" on center (2 5/8" between bars). Enamel coated black. Our model CM445 panel accepts any lumber up to 3/4" thick.
