Carbo T2 Soft-Attach Air Blocks

Made of a tough reinforced composite the carbo air blocks or also know as pulleys are smooth-running and powerful performers, making trimming easy regardless of wind power. They are perfect for main, jib and spinnaker sheets on dinghies and sportboats control lines of boats of all sizes. High-strength, lightweight fiber-reinforced composite construction the open air blocks are designed to eliminate unnecessary material to reduce weight while being UV-stabilized (ball bearing, sheave, and sideplates) they stand up to sun, salt and time. The free running ball bearings roll on curved races dispersing the load for a higher strength block offering a low friction efficiency for fast trim and release. The ball bearings of the T2 Carbo Air Blocks range are made of a Delrin UV-staibilized acetal resin while the sideplates and sheave are made of a carbo composite material.
