Description

The Harken Carbo Air 75mm Single Swivel Block is a high-strength, lightweight marine pulley designed for smooth and efficient rope handling in demanding sailing and boat rigging applications.

Featuring a 75mm ball-bearing sheave and a versatile swivel attachment, this block provides reliable performance and excellent load distribution. Its fibre-reinforced composite construction offers an outstanding strength-to-weight ratio, while the open AirBlock design eliminates unnecessary material to reduce overall weight.

The swivel attachment can lock into front or side positions or rotate freely, helping prevent rope twisting and allowing the block to align with different rigging configurations.
