These replacement fin rails are ideal for extending the lifetime of your diving fin. Sold by the kit, the Neptonic Sytems replacement rails contain four upper rails and four lower water channels. At 13 inches and 15 inches long, our lower and upper fin rails are long enough to fit any fin on the market.
Rail fins are used to channel water down the diving fin blades, creating more effective strokes. When rails are finally come loose or are worn out, fins may loose their effectiveness. With our fin rail replacement kit your fins perform well again.
For application we recommend using super glue gel.
