US i-FIN screw for SUP fin
US i-FIN screw for SUP fin is a stainless steel screw with a fixing plate. It locks the fin in the US i-FIN box of an inflatable SUP board. If you lose the screw, the board is left without a fin, so it is worth keeping a spare in your backpack.

Key features
✓ Stainless steel – corrosion resistant in fresh and salt water
✓ Screw and plate – a complete fixing set
✓ US i-FIN standard – fits most inflatable SUP boards
Installation
How to fit the fin
Insert the fin into the groove of the fin box, slide the plate under it and tighten the screw by hand or with a coin. Do not overtighten, so you do not damage the plastic box. If you need the fin itself, choose the Amber Basic fin.
