Harken Block 16mm with swivel, sailing accessories, high working load minimal friction

Harken's 16 mm block series is ideal for thin control lines, such as those used on high-tech dinghies. The bearing system consists of stainless steel balls in a grooved raceway with a cage. The blocks boast an impressive maximum working load for their size, with minimal friction. Thanks to the swivel, the 16 mm block always aligns with the line and is suitable for control lines with loads from changing directions.
