Boating Essentials Telescopic Boat Cover Support helps anglers keep the cover tight and water moving off the boat after long bass, walleye, salmon, or crappie trips, so the deck and cockpit stay better protected between launches. This aluminum support adjusts from 28 in. to 48 in. for a better fit across a wide range of boat covers and hull layouts, giving boat owners a practical way to reduce sagging and limit water pooling during storage. Tool-free installation makes setup simple, while the wide mushroom-style top cap spreads support under the cover and the non-skid rubber bottom helps keep the pole planted in place.
