Streamlined Red-Line Aluminium Mast Extensions



More Info
Streamlined mast extensions and accessories are the benchmark in high performance windsurfing accessories.
The “Red-Line” extensions are engineered to be used even at their longest setting. Most windsurfers are cautious to use the longer settings on their extensions due to bad experiences with other brands. With Streamlined Redlines’s, you can sail them at the full 30cm or 46cm extension heights with full confidence.
The extensions have a unique alloy of 6061 T-8 drawn aluminum tubing. They are precision machined, anodized red, inside and out, and have permanent numbered increments every two centimeters.
All extensions feature a secure, fool proof adjustment pin tethered to a hard anodized aluminum collar. They all incorporate the ultra strong, powerful “Quick-six", quick to rig, six to one, downhaul cleat system and downhaul line.
Available in 30cm, 46cm, Reduced Diameter, Standard Diameter, Euro Pin and Double Push Pin, there is one to suit your need.

BIGSURF OPINION
These extensions feel seriously solid...you can tell they are built for strength just by holding them. Serious quality components used throughout, with all parts being replaceable, so you can rebuild them any time you want. This also means they hold their value really well. The pulleys mounted at right angles to the mast also mean no twisted rope, so simple downhauling. One of our favourite windsurfing components...ever!
