Get the fit right

Three checks.
One correct setup.

The right construction is only part of the choice. Match the extension to the equipment you actually sail.

Match your mast.

Choose RDM for an RDM mast and SDM for an SDM mast. These are separate diameter options. Check your mast’s specification before selecting a variant.

Check the setting.

Use your sail’s recommended mast and extension setting. The required setting must sit within the extension’s marked range. Keep the required insertion inside the mast.

Match your method.

Double Cleat suits a compatible winch. XXL Pulley prioritises manual downhaul. Choose Carbon Pro when reducing weight matters, and check the connection to your mast base.

Which extension should I choose for downhauling by hand?
ALU+ Double XXL Pulley is our recommended aluminium option for manual downhaul. Its two large pulleys and open cleat give the rope a freer path. Carbon Pro also uses oversized rollers and an open cleat, with carbon construction for riders who prioritise weight.
Is Carbon Pro worth the extra cost?
Choose it when reducing rig weight is a priority and the premium fits your budget. Weight saved at the foot of the rig is less noticeable than at the head or clew. If your main goal is easier manual downhaul, the aluminium XXL Pulley is a practical starting point.
Can I use my existing downhaul winch?
Check the fit of your exact winch before ordering. Double Cleat is our recommended system for compatible winch use. The XXL Pulley’s open-cleat design does not suit every winch. For Carbon Pro or an unfamiliar tool, ask the team to confirm the combination .
