NRS SUP Board Fins let you customize your board for the type of paddling you're doing. Shallower ones for quick turns and rocky streams, longer ones for straight-ahead tracking. Three interchangeable sizes to choose from.
2", 5" and 9" deep fins are interchangeable on NRS SUP boards and other boards that use the same holding plate: Item #86104.01.
Fins are made of a rugged nylon-reinforced plastic that can take the hard knocks of stand up paddling.
Base of the fins is 1 3/8"W x 7 3/8"L.
A tethered locking tab holds the fin securely in the plate.
