Camco's Boat Cover Support Kit is an easy-to-use telescoping support system that keeps your boat cover from sagging and allowing water to pool. This helps extends the life of your boat cover. The Boat Cover Support is self-standing with support plates on the top and bottom. The bottom support plate has a foam pad to protect the boat and stop sliding. To accommodate different styles of boats, the Boat Cover Support has an adjustable height from 30-inches to 50-inches in 2 ½-inch increments. The nylon strap assembly is 50-feet long and fits most boats up to 22-feet in length. This product is easy to install and stores compactly when not in use. Camco also makes a full line of attachments that can be purchased and used with the telescoping support pole.
