46cm Red-Line Extension for SDM and US base cup - Red-line extensions start with custom 47 millimeter, 6061 T-8 “drawn” aluminum tubing. The kind of tubing they use to make aircraft. Our tubing is engineered so that with its large diameter, the wall thickness can be thinner so the overall result is an incredible high strength, to low weight ratio. This formula has been proven with our years of experience. The holes are precision punched, then the tube is red anodized in and out, permanent laser numbered 2 centimeter settings. The adjustment settings are held with a hard anodized aluminum collar tethered with a spectra line to a stainless steel pin. Fail-safe and virtually break proof. Finally we attach our new beefy “Power-Six” super powerful 6:1 downhaul cleat with large diameter pulleys, perpendicular for power, easy rigging and no crossed lines. An 8-plait Dyneema downhaul line is included.
