29 mm Blocks
About Carbo Air blocks: see feature page at 
beginning of this section.
Use as becket block without the 
additional height of a becket.
Doubles and triples feature U-Locks 
to hold the swivel in front/side 
position, or to let it spin freely.

High-strength pivoting lead blocks 
with cams are used for halyard 
controls on larger keelboats and as 
“headknockers” on dinghies and 
beachcats for sheeting directly from 
the boom. Hole spacing and rivet size 
are the same as Classic models, 
making upgrades easy. Cam reverses 
for either up or down cleating. 
*Can be used as becket block.     **Maximum working loads and breaking loads for blocks based on cam strengths.
