Streamlined's Red-Line extension have proven their amazing durability throughout the years. They resist the massive tension applied on race sails even at their longest setting, so strong that they come with a 5 years warranty

Red-Line extensions have been reviewed and come with the new "Power-Quick6” a super powerful 6:1 downhaul cleat with large diameter pulleys made of strong self-lubricated POM. These pulleys are perpendicular for power, easy rigging and no crossed line.
