Multiple rows of high-load ball bearings and precise V-shape reduce friction, allowing Harken cam cleats to activate with the snap of the wrist.

Harken cleats are the only cleats that engage under maximum line tension.
The double cam-matic cleat is designed to make double sheet (coarse fine) control simple
