Mast Extension Heavy Duty SDM U-Pin 30-32cm Unifiber SC000100130

Description:

The Unifiber Heavy Duty SDM mast extension is engineered to give windsurfers a reliable, strong and easy-to-adjust connection between mast and boom. It combines a superior-quality polyamide base and collar with a lightweight aluminum extension tube to deliver high strength without unnecessary weight. The collar uses Unifiber’s Polyamide "Open, Twist, Slide & Lock" system for fast, secure rigging and positive locking under load. Supplied with a standard 4 mm polyester rope, the extension is ready for immediate installation and trimming on SDM-compatible rigs. Its robust materials and corrosion-resistant construction make it durable in harsh saltwater environments, while the compact 30–32 cm range provides precise sail tuning and consistent performance. The U-pin style fitting ensures compatibility with most SDM systems and allows easy interchangeability with existing booms and mast bases.
