Harken 16mm Blocks

Harken Blocks

Harken 16mm Blocks

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) safe working load—the highest on the market compared to similarly sized blocks.

The 442 uses a spacer and the 404 uses an O-ring to keep the line in the sheave during intermittent loading.  The 467 uses a narrow sheave for extremely small control lines and has a ferrule head for soft attachments.
