Streamlined standard diameter aluminum extension, US Cup. With ball bearing rollers for reduced downhaul effort.
Streamlined's new “Red-Line” extensions are engineered to be used even at their highest mast setting. This makes their extensions extra versatile compared to other brands. With Streamlined “Redlines’s", you can sail them at the full 30cm or 46cm extension heights with confidence. The new redline extensions evolved from Streamlined's “Super-lite” line, tried, tested, and proven for years. They start with Streamlined's own unique 6061 T-8 drawn aluminum tubing, made in the U.S.A. They are precision machined, anodized red, inside and out, and have permanent numbered increments every two centimeters. All of them have a secure, fool proof adjustment pin tethered to a hard anodized aluminum collar. Naturally they all incorporate Streamlined's ultra strong, powerful “Quick-six", quick to rig, six to one, downhaul cleat system and downhaul line.

Extension range 6 to 30 cm in 2 cm increments.
