ABOUT

The winch is made of sea-waterproof aluminium and additionally protected against corrosion by an enamel finish.
A counting wheel allows to read out the length of wire paid out. Zero setting is possible. The rope can be fixed at any desired depth. A heavy double-screw steel clamp allows for easy fixing at the walls of boats, bridges, rails, well pipes, etc. Rope can be ordered separately at any length up to 200m.
