Features: Revolutionary interlocking cam action automatically locks pole in place. The pole cannot accidentally be released by even the hardest fish strike, snag or trolling or boat rolling - or by any other angular action of the rod handle end. One-finger "snap-slide" allows Pole-Lock to be rotated - or used right or left-handed - or removed to install a boat cover. Mounts flat or on 20º angle block (included for high rod tip position) Holds all styles of fresh and salt water rods up to 5/8" diameter at the handle regardless of reel or handle style. Mounts on boats, docks or anyplace handy. Rugged, corrosion, resistant polymer won't mar your expensive graphite or boron rods. No springs to break, wear out or lose. No tricky in-or-out motions to learn
