H406 16 mm Doppelblock

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 race with a cage. The blocks boast an impressive maximum working load for their size, with minimal friction. The 16 mm double block is suitable for 3:1 or 4:1 ratios.
