HARKEN Carbo Air Block | T2 Composite Sailing Blocks

The HARKEN Carbo Air block family is built on high-strength T2 composite construction—the first block design with no metal shackles or rivets—providing a lightweight, low-friction solution for a wide range of sailboat control systems. Carbo Air blocks are companions to the Harken Black Magic line and are intended for traveler controls, mainsheets, vangs, cascades, bridles and other systems where small, compact, strong blocks are required. The range includes multiple sheave sizes (including 29 mm, 40 mm and 57 mm) and attachment styles such as fixed, swivel, ratchet, cam cleat, becket and soft-attach to meet various rigging needs. Each unit ships with a length of Spectra line and delivers high working loads for reliable, easy trimming and handling.
