This 4.5" fiberglass fin fits in any standard medium center box and allows you to set your 2 1 board up as a thruster. This is a great option for our 2-FUN mid-length board.

***Please note, all of these fins are HANDMADE by Rainbow Fin Co. and there will be variation in the color from what you see on your screen vs what is received. We do our best to photograph the fins to represent the actual color, but they won't be an exact match. We do not accept returns based on color variation.***
