The Lee's Tackle Inc. Swivel Base Rod Holder is the ultimate rod holder for serious sportsmen. Its unique swivel base allows the rod butt to rotate in the holder when side pressure is applied to the tip of the rod, making it an indispensable tool for Giant Blue Fin Tuna fishing and reducing the possibility of line fraying. This medium size short swivel base is designed for stand-up rods with curved butts and has a 2" OD x 6-1/2" long tube. The amount of torque required to rotate the swivel is adjustable by adjusting the pressure on two nylon drag washers with a 1/2 inch stainless steel lock nut at the bottom of the holder.Specifications Half Angle 15° Short Tube Medium length Features Swivel base allows rod butt to rotate Reduces possibility of line fraying Adjustable torque for rotating swivel Designed for stand-up rods with curved butts
