Winch Block with ø57mm Ball Bearings Port + Swivel
Discover the Nautos Line Series performance block range, designed to meet all onboard needs. Robust and ultra-smooth with their ball bearings, these blocks offer excellent resistance to effort and maximum efficiency in all configurations.
From ø28mm to ø75mm, available in a very wide range, they are suitable for both dinghies and cruising boats.
The winch block will allow you to hold the genoa or spinnaker sheet perfectly. With its disengageable ratchet, you can choose according to the tension. The grooved aluminum sheave is designed to allow easing and trimming without constraint. To be positioned to starboard for a port tack: clockwise rotation!
