The Frost King DE200 is a 6-foot rollout extender that automatically unrolls under water pressure and rolls back up when dry — directing runoff well away from your foundation without any effort. It fits universally on 2×3-inch and 3×4-inch downspouts and is made from durable black polyethylene that resists UV degradation over seasons of use. A simple, inexpensive first line of defense against foundation water intrusion.
