The Extend-A-Line is designed to be mounted to 1" or 1-1/2" exterior ladders with 9-5/8" to 10-1/8" spacing between the upright tubing. Six independent arms can carry towels, suits, or clothes on hangers and support 10 lbs. per arm with a 60 lb. maximum load when evenly spaced. Each arm spans 27" of useable reach. Wall-mounted bracket provided for home use or RVs without ladders. Chrome-plated arms and a plastic body resist rust.
