Step 1:
Start by loosening your single tab fin screws with a fin key.

Step 2:
Identify each fin and its required location. The centre fin should sit up straight whilst the side fins should taper slightly towards the rail.

Step 3:
Insert the fin into the fin box (tail end first) ensuring the fin locates into the groove.

Step 4:
Once the tail of the fin is located, push the fin backwards and downwards to locate the fin into the fin box.

Step 5:
Tighten fin screws for a firm fit.

Step 6:
Go shred!
