Mounting Hardware is NOT included! A Sea-Lect, aka Sea Dog product. This paddle holder allows for simple one-handed stowage of your paddle, with leash attachment points for securing a fishing pole leash. The shape prevents fish line from getting snagged (the use of well-nuts may defeat this! Rivets are recommended). Secures with two; screws and nuts or rivets. Mounting Hardware is NOT included! Screw holes are 4 inches on center. Paddle holes are 1.25 inches high, 2 inches at the widest (middle) and 6 inches long. (Sea-Lect part #K737361)
