Neptonics Replacement Fin Rails

Overview

Neptonics Replacement Fin Rails are a universal replacement kit for freediving and spearfishing fin blades. The kit provides the rail sections needed for a pair of fins, with different profiles for the blade tip and foot-pocket areas.

Design and fit

The channel sections install toward the blade tip to direct water along the blade, while the lower-profile sections are used toward the foot pocket. The supplied sections are long enough to be trimmed to the required blade length, allowing the kit to accommodate different fin blades without a dedicated size selection.

Installation

Cut the rail sections to the required length before securing them to the fin blade. Super glue gel is recommended for bonding the rails.
