Designed to survive under heavy load, the HD SDM+ extension is a quality piece of equipment in every racer’s arsenal.
Rigid and sturdy, all parts of the extension are toughened to give a piece of mind even in the gnarliest situations.
The main tube is manufactured from hardened T6 aluminium while the nylon base is fiber-reinforced. The connection between both parts is further fortified using a stainless steel insert.
The base features a 3-roll pulley that significantly reduced the effort required from the user to downhaul bigger sails sizes.
Pulley/cleat system orientation makes rigging easy and intuitive.
