The Hollow Point fin was devolped to replace your standard trailer fin on a thruster setup but has been proving to be even better for the rears on a quad fin setup! The "FULL BOX" mounting system is for 1/2" deep fin boxes. The thruster setup is for 1 Hollow Point fin and the quad setup is for 2 Hollow Point fins.
*CLICK-IN SYSTEM IS IN DEVELOPMENT*
**Color pattern will slightly vary from fin to fin**
CARBON cannot be combined with colors
