From the Manufacturer Werner aluminum extension planks come in three sizes: 6-foot to 9-foot, 8-foot to 13-foot, and 10-foot to 17-foot. These convenient, easy-to-store extension planks have a 250 pound duty rating. They have positive stops every foot, which also prevents over-extension. Made of 2-inch deep box section extrusion, each extruded cross member is riveted with solid aluminum rivets. Molded thermo-plastic spacer guides provide easy open and close action. The outer flange is open for ladder jack clamps.
