40mm Carbo Air® Cheek Block. Low-friction 40mm Carbo Air® blocks are lightweight, strong, reliable—and affordable. 30 percent lighter and 60 percent stronger than equivalent Classic blocks. Sideplates are UV-stabilized, high-strength resin. Ball bearings made from engineered plastic in fitted ball races. Designed for small-diameter lines favored by racers. 

Use 40mm Carbo Air® blocks for jib and mainsheet systems on high-performance dinghies, and for high-load control lines on small keelboats. The 40mm blocks handle loads similar to Harken's 2 1/4" blocks. Recipient of both the Dame Award and Sail Magazine's Freeman-Pittman Award for innovation.
