Mast Extension Heavy Duty RDM U-Pin 45cm Unifiber SC000100050

Mast Extension Heavy Duty RDM U-Pin 45cm Unifiber SC000100050

Description:

The Unifiber Heavy Duty RDM Mast Extension is a 45cm U‑Pin extension designed to increase mast length and improve rig tuning for RDM windsurfing setups. Its primary function is to provide a super‑stiff, reliable connection between mast and boom while allowing quick height adjustments and secure U‑Pin locking. Constructed from an aluminium tube with a reinforced plastic base and extra stainless‑steel reinforcement between the base and tube, this extension is built to withstand hard use and harsh weather. The reinforced junction reduces stress and the risk of base failure, delivering consistent performance in demanding conditions. Riders will notice improved stiffness and more predictable sail behavior, which translates into better control and power transfer when planing or sailing in strong winds. The Heavy Duty extension is especially suited to sailors who need durable, long‑lasting gear for regular or extreme use and is compatible with standard RDM mast setups using a U‑Pin locking system.

Key Features:

• Heavy‑duty aluminium tube for high stiffness and strength
• Extra stainless‑steel reinforcement between plastic base and aluminium tube for improved durability
• Reinforced plastic base to resist cracking and wear under load
• U‑Pin locking system for secure, quick attachment and easy tuning
• 45 cm length provides significant extension for larger sail setups or tuning range
• RDM (Reduced Diameter Mast) compatible design
• Corrosion‑resistant materials for extended life in marine environments
• Designed for consistent performance in tough weather and heavy‑use conditions
