The 16mm 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 442 uses a spacer to keep the line in the sheave during intermittent loading.
Note: DO NOT use Harken equipment for human suspension unless product is specifically certified and labelled for such use.
