All of our standard air and hydraulic-release hooks provide good dampening against the sudden shock of line release under load. These rotary-release models, though, go a step further. By spinning freely, they remove the strain from the hook itself, rather than using a bumper pad to absorb recoil. This provides for smoother release and allows the hooks to handle higher loads.
In addition, the smoother release prolongs the life of both the hook itself and the mooring lines it handles. Of course, like our other models, rotary release hooks are made of heat-treated alloy steel, are hot-sprayed with zinc before finishing, and include the same safety features and ease of maintenance.
