Mast Extension Heavy Duty RDM U-Pin 32cm Unifiber SC000100080

Mast Extension Heavy Duty RDM U-Pin 32cm Unifiber SC000100080

Description:

The Unifiber Heavy Duty RDM mast extension is a 32 cm, U‑pin style extension engineered to give windsurfers a stiffer, more reliable connection between boom and mast. Its aluminium tube is bonded to a reinforced plastic base with an extra stainless‑steel insert, delivering exceptional stiffness and resistance to torsion under load. The heavy duty U‑pin and stainless components improve corrosion resistance and provide a secure lockup in demanding conditions. This construction reduces unwanted flex in the rig, helping to maintain cleaner sail shape, improved power transfer and more consistent handling. Designed for use with RDM masts and standard U‑pin boom fittings, the extension offers peace of mind in rough weather or high‑load sailing. Easy to install and robust enough for intensive recreational or competitive use, it’s a reliable upgrade for riders who need durability and precise rig behaviour.

Key Features:

• Heavy duty design for extra stiffness and load capacity

• Maintains sail shape and improves power transfer by reducing mast flex
