Maximum performance, maximum durability. Whether you're blasting on heavy chop or bombing mast-high waves, you can rely on this mast extension. The pre-preg carbon tube keeps the weight low and gives a responsive feel to your rig. The direct connection between the pre-preg carbon tube and the stainless steel base is stiff, solid and extremely durable. The open-and-slide collar allows for one-handed length adjustment and the flat base is bare-foot friendly.
