Ideal support for mainsail trim. The boom no longer pulls down unintentionally and thus the mainsail out of the profile. For trailerable boats, training boats and day cruisers. No drilling required during installation, no maintenance and adjusted in minutes. No modifications need to be made to existing tackles. Does not represent a restriction for boom furling systems. Rod length (axis-axis): 76.2 cm. Max. Working load: 35 kg.
