Low-friction Carbo Air blocks are lightweight, strong, reliable—and affordable. Companions to our popular Harken Big Boat blocks, these small, compact blocks have very high working loads for safe, easy trimming. Lightweight nylon resin sideplates replace stainless steel straps found in Classic blocks. Densely packed glass fibers reinforce resin for strength.
Carbo Ratchets allow sailors to hand-hold loaded lines and offer balance between holding power and controlled easing. On/off switch operates from both sides. Standard grip: medium/light air; 10:1 holding power

Shackle blocks lock in two directions or swivel to keep line from twisting
Cam-Lock or U-Lock allows shackle to be fixed or to swivel.
Low-friction efficiency for fast trim and release

Free-running ball bearings roll on curved races, efficiently dispersing load for a higher strength block.
