The 75 mm Carbo AirBlocks® are a 2-15/16" diameter low-friction, lightweight, strong, reliable and affordable block. Working loads range from 408 Kg for the Harken 2696 Fiddle Ratchet, up to 1,650 Kg for a Harken 2664 Triple.
Companions to the popular Harken Big Boat blocks, these compact blocks have very high working loads for safe, easy trimming.
Lightweight, strong and reliable fiber-reinforced composite construction sideplates replace stainless steel straps. These densely packed glass fibers reinforce the resin for strength.
These smooth-running powerful performers make trimming easy, no matter how hard the wind blows.
75mm Carbo AirBlocks® are of a size and style that will fit any system: Singles, Doubles, Triples, Ratchets and Fiddles.
Perfect for main, jib and spinnaker sheets on dinghies, sportboats and small keelboats; and control lines on boats of every size.
Ball bearings, sheave, and sideplates are UV-stabilized.
The machined anodized aluminum sheave has eight facets to hold the line securely and provides up to 15:1 holding power with a 750-pound safe working load.
The Carbo Ratchamatic® is a load-sensing ratchet block with a 15:1 holding power that rolls freely in both directions under low loads and automatically engages the ratchet as loads increase.
This switchable 75mm Ratchet block provides up to 15:1 holding power and provides precise on/off control with accessible, easy-to-operate switches on both sides of the block.
