The main body of the pulley is made of anodized aluminum, which is not only corrosion-resistant but also extremely durable. This material also comes in 5 colors, so there is something for everyone.
The axles are composed of polished stainless steel that is very durable and accents the colors as well.
The wheels are made of a polymer that is designed to minimize friction and give the user total control when pulling or releasing the line.
Its perfectly calibrated geometry provides complete control and reliability, so you don’t have to worry about the rope slipping when diving.
The pulley works best with the standard 10 and 12 mm rope.
