Mast Extension SDM U-Pin 15cm Unifiber SC000100090

Description: The Unifiber SDM Mast Extension U-Pin 15cm is a reliable, user-friendly extension designed for beginner and recreational windsurfers who need simple, robust downhaul control. It features a reinforced nylon base and a three-roll pulley system that makes rigging smooth and efficient while minimizing rope friction. The base is generously sized so you can rig comfortably even barefoot, and the cleat is positioned for easy access so the downhaul can be released with a single jerk. The U-pin type lock provides a secure, positive connection to the mast butt while remaining quick to install and remove. Built for everyday use, this extension balances durability and simplicity to keep on-water setup fast and predictable. Compatible with standard SDM masts and most SDM-compatible booms, it’s ideal for school gear, rental fleets, and casual sailors.
