57mm Harken Carbo Ratchet Triple, 150 Cam-Matic, 40mm Block, Becket

The Harken 57 mm Carbo ratchet triple block with 150 Cam-Matic cleat, extra 40 mm block and becket is a complete lower block for a mainsheet purchase. As a Ratchamatic®, the ratchet is load-sensing: under low loads the block rolls freely in both directions, and as the load builds the ratchet engages automatically. You can hold the loaded sheet by hand and ease it under control.
