Description:

The Unifiber RDM Mast Extension 45cm is a dependable, user-friendly extension designed for recreational and beginner windsurfers who need a simple, durable way to tune sail downhaul and rigging length.

Overall this extension balances robust construction with practical ergonomics to improve rigging speed and reliability during everyday windsurfing.
