4'6" US BOX RIVER FIN
A universal, curved fin, 4'6" (11.7 cm) long, designed for inflatable SUP boards with a US Box centerboard.
Made of a flexible material, it has the right stiffness for effective board control and is very flexible to minimize the risk of damaging the board's bottom when hitting an invisible obstacle. The fin literally glides between obstacles.
It is mounted to the US Box centerboard using a steel screw with a cover, included with the fin. The US BOX system on some SUP board models allows you to adjust the fin's position in the box and change the board's ride characteristics.
A forward fin increases the board's maneuverability. A river stabilizer is used when the water level in a body of water is very low or unstable, or when there are invisible obstacles submerged underwater, such as tree limbs, fallen trees, boulders, or stones.
