Harken's smallest AirBlock, the 16mm 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. The safe working load of 250lbs is the highest on the market for similarly sized blocks.
It is great for dinghy control lines, big boat leech lines, downhauls, traveler controls, spinnaker pole trip lines, outhauls, cunninghams, and halyards on prams. For instance, Snipes use one in the jib downhaul system.
This block has an O-ring, which keeps the line on the sheave during intermittent loading.
