Description
After a long design process with 3D modelling and countless trials and tests, we created a mast extension with a great design and top-level, high-quality technological solutions.
The extensions come in three different materials: aluminium, ergal and 100% carbon; below is the technical data sheet to understand the differences.
1 -the extension tube is made from a single piece, reaching all the way down to the bottom of the plastic base cup
2 -the pulley bracket and cam cleat are a single stainless steel casting
3 -the cam cleat is angled in line with the pulleys to allow optimal sail trimming, avoiding rope twisting and ensuring a firmer hold.
4 -the pulley bracket is fixed directly onto the extension tube
Material used for the tube: 7075 alloy
MECHANICAL CHARACTERISTICS:
Tensile strength Rm(N/mm³): 540
Yield strength Rp 0.2: 485
Elongation A5: 6
Hardness HBS: 153
