Adjustable Collar SDM HD Mast Extension Unifiber UF600000047

Adjustable Collar SDM HD Mast Extension Unifiber UF600000047

Description:

The Unifiber Adjustable Collar for SDM HD mast extensions is a precision collar designed to provide secure, deformation-resistant support under extreme downhaul loads. Constructed from high‑strength, durable materials, the collar reliably maintains mast alignment and structural integrity even when tensions are at their maximum. Its intuitive "open, twist & slide and twist and lock" functionality allows fast, one‑hand adjustment and an audible positive lock once set. Low‑profile geometry minimizes interference with the rig and reduces chafe on lines and harness components. The robust construction and smooth operation deliver consistent sail trim and improved control in demanding windsurfing conditions. Engineered for longevity, this collar resists wear and maintains performance over repeated use. It is specifically compatible with Unifiber SDM HD mast extensions and integrates seamlessly into most SDM windsurfing rigs.
