29mm Carbo AirBlock Cheek Block

High strength engineering plastic used in the sideplates, sheave and balls allows us to make blocks 60% stronger and 30% lighter than our classic blocks. Use Carbo AirBlocks with small diameter hi-tech lines on high performance dinghies, small keelboats and catamarans. Using small, light, high strength Spectra line, attach these blocks to eyestraps, booms, fiberglass side tanks, and traveler cars, and eliminate the weight of shackles, swivel posts and stand-up springs. A comprehensive instruction manual details the many methods of attaching the blocks. Doubles and triples feature M-Lock to hold the swivel in front/side position, or to let it spin freely. The triples compact cam arm supports high load purchases of 5:1 or 6:1. The line shedding cheek block features a small mounting footprint and drainholes. Sheave 1-1/8", Max. Line 5/16".
