This Attwood Boat Cover Support Pole provides easily adjustable support under a boat cover to keep the cover elevated in the center to promote run-off of precipitation and prevent water from pooling atop the cover. This 1-In. diameter anodized aluminum pole can be adjusted between 28 In. and 48 In. It locks and unlocks easily at the desired length with just a twist, no tools required. It has durable rubber tips at both ends that protect the boat and the cover, and ensure the pole remains properly positioned where you set it.
