OBD Fin Double T-rail incorporates both the low profile T to lock tendons of footpockets on and the wider water cahnelling rail. This means one simple process, with less cutting and measuring and easier to glue on.

Provides a much neater finish, plus enhances water channeling because the wide portion continues the full length of the fin blade.

• Price is per 10cm of length - measure and order the continuous length you need, without wastage.
• Most fins require around 62cm to 72cm per side so you will require 4 times this, for a pair.
• Order the right amount, without having to throw excess away.
• Allows easy fit into foot pockets with T-shaped internal channels.
• For new bare blade assembly and builds.
• Replace worn or broken side rails on your fin blades.
