421 16 mm Single Thru-Deck
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 )-ring to keep the line in
the sheave during intermittent loading.
Use for:
Dinghy control lines
Big Boat leech lines
Downhauls
Traveler controls
Spinnaker pole trip lines
Outhauls
Cunninghams
Halyards on prams
