Low-friction Carbo AirBlocks®
are lightweight, strong, reliable and affordable. Companions to the
popular Harken® Black Magic® line, these small, compact blocks have very
high working loads for safe, easy trimming.
The 40mm fiddle is an excellent 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.
