Big Jon's Single "Heavy-Duty Ratching Diver Rod Holder" is a popular rod holder for use with diving disks; for good reason, not only is the most solid rod holder we build, it is easy to use, and you can adjust it to any of nine positions, with a positive locking latch pin! This model of diver rod holder "Ratchets" to the vertical position when you pick up your diver rod. No more reaching over the side of the boat! It features a 4 in. x 2 1/2 in. slim-line base, that is ideal for narrow mounting surfaces. Big Jon precision machines this rod holder from high-strength aluminum, for a perfect fit and smooth operation. It is given a bright anodized finish that will resist corrosion and then it is fitted with durable vinyl caps to prevent wear to your fishing rod handles.
