"These fiberglass whips are exceptionally strong, attractive and will not obstruct your waterfront view. Acting as a spring, each whip is comprised of a solid, fiberglass rod, durable cast aluminum bases with a tough 3/8" thick mounting footprint and molded-in cleat and ring and thumb screw for securing the whip into position. Unaffected by UV, each whip also includes a unique tip with functional roller to allow easier access to your boat. Great for PWC's also. Sold as pair."
