The Harken 16 mm Block is the
smallest block available from Harken. It is perfect for
small synthetic control lines found on high-tech dinghies.
The Harken 16 mm Blocks patented bearing system uses stainless steel balls
in a captive grooved race and has a 250 lb (113 kg) safe working load - the
compared to similarly sized blocks.
The HAR442 uses a spacer and the HAR404 uses an O-Ring to keep the line in
the sheave duringintermittent loading.
The HAR467 uses a narrow sheave for extremely small control lines and has
a ferrule head for soft attachments.
