Standard Screw 3-Fin Replacement Set (4.5")

Three of our safety fins with the screws designed to fit Rock-It Chub (4'10"), Softy (8'), and Moby (9') boards. 

This fins are universal with most other screw-through soft top surfboard brands.

We have three different sizes--the fins are all 4.5", however the screw length is different between the three sizes to accommodate for thicker boards as the boards are larger.   

Rock-It Surf screw through fins are more rigid than many competing fin sets, allowing for higher performance and harder/more accurate turns since there is less flex in the fin.  All fins are 50/50 foiled.
