The 16 mm is Harkens® 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 442 uses a spacer to keep the line in the sheave during intermittent loading.
