The 16 mm is Harken’s smallest block. It is perfect for small synthetic control lines found on high-tech dinghies. The patented bearing system uses stainless steel balls in a captive grooved race and has a 250 lb (113 kg) maximum working load.

The perfect block for Waszp/Moth and other control tail away systems, but also commonly seen on Finn + OK halyard systems - just amazing value block!

A great innovation that allows you to raise and lower the bailer whilst remaining hiking. For Finns and OKs - with two bailers, of your bailers should be this one!

The perfect auto bailer for Finns, OK, 420 - mount from inside and able to be fully faired.
