Our top engineers have spent the last three years trying to figure out a way for riders to buy our fins without having to throw down an additional $10 on hardware at the same time. After years of R&D we believe that they have finally hit it. CDI introduces the first economic alternative for attaching your fins to your board - the CDI 4-pack.

Hardware packs are available in two sizes: 3/16" or 1/4". The standard for most boards is 1/4". We also offer the 3/16" hardware for the few companies that use the narrower bolt.

Here’s what you get:
- 4 screws
- 4 plastic washers
- 4 metal washers
- $$ left in your pocket!
