The outer diameter of the upper mast cap is larger than the diameter of the extension tube. This, combined with the stepped collar of the Clamshell, creates a cavity thus preventing the carbon mast and alloy tube to be in contact, preventing oxidation and corrosion.

Easy, user friendly operation in all temperatures.
Heavy duty stainless steel construction - designed to sustain high loads.
Positive engagement - completely unaffected by sand.
Increased tube strength due to the absence of any grooves.

High quality pre-stretched marlow rope.

The rope cleat is integrated into the stainless caste structure and is perfectly aligned with pulleys for streamlined profile, maximum strength and reduced friction of lines.
