Aluminium Mast Extension HD RDM U-Pin 45cm Unifiber UF030035050

Aluminium Mast Extension HD RDM U-Pin 45cm Unifiber UF030035050

Description:

The Aluminium Mast Extension HD RDM U-Pin 45cm from Unifiber is a heavy-duty mast extension engineered for high-performance racers and aggressive wave riders. Its main tube is manufactured from hardened T6 aluminium while the base is made from fibre-reinforced nylon, delivering a rigid, impact-resistant assembly that stands up to extreme loads. A stainless-steel insert fortifies the connection between tube and base and the U-pin locking system gives quick, secure attachment to RDM masts. The pulley/cleat system orientation is intuitive, making rigging fast and reliable even in challenging conditions. The stiff construction reduces unwanted flex for more direct power transfer and precise sail trim, improving control and performance. All parts are toughened for durability, lowering maintenance and extending service life. At 45 cm it provides additional mast length without compromising stiffness and is compatible with standard RDM masts and most boom fittings.
