This low-friction Carbo Air Block from Harken is lightweight, strong, reliable and affordable. Similar to Harken's Black Magic line, the small and compact sailing block has a very high working load for safe, easy trimming.
This 40mm fiddle block is a superb choice for 3:1 and 4:1 tackles on dinghy vangs and mainsheets, as well as for controls such as cunninghams and internal boom outhauls on larger boats.
