SDM PERFORMANCE

Our proven SDM extension is now available in carbon for maximum performance.

Aligned triple pulleys make it easy to thread the downhaul logically and provide extra leverage to reduce the effort required to downhaul your sail. Dyneema rope is used to further reduce friction.

Reliable stainless steel mechanisms and low-profile hinged collar make this a quality piece of racing equipment.
