When your sail requires solid downhaul tension, HD SDM extension is the right tool for the job.

The base itself is made out of high-quality polyamide to withstand the high-tension downhauling. Featuring a 3-roll pulley, the extension decreases the effort required from the user to downhaul even a slalom sail.

The functional length can be adjusted with one hand using the open-and-slide-collar
