C. Sherman Johnson 1/8 in Over-Center Gate Hook

The C. Sherman Johnson 1/8 in Over-Center Gate Hook is a lifeline gate fitting designed so the swinging hook is not carrying the main load when the mechanism is closed. That over-center geometry helps the gate open more easily because the hook is not wedged under lifeline tension. A heavy split ring on the plunger provides the retaining action that keeps the closed mechanism secure. The fitting is intended for 1/8 in wire lifeline systems using the matching threaded connection.

The threaded end uses a 1/4-28 left-hand connection and provides 1-1/4 in of adjustment. That travel gives the installer room to set gate tension and compensate for the exact spacing between stanchion fittings. Investment-cast construction produces the complex hook and latch shape as a single durable assembly. Because the load path is controlled by the over-center mechanism, the gate can remain secure without making normal opening unnecessarily difficult.

• Over-center geometry removes load from the swinging hook when closed
• Heavy split ring secures the plunger latch
• 1/4-28 left-hand threaded adjustment
• 1-1/4 in of adjustment for gate setup

Confirm the mating thread direction and wire-terminal arrangement before replacing an existing gate hook. After tensioning the lifeline, verify the hook closes fully and the retaining ring engages without binding. Browse more Sailing Hardware for compatible hardware and related marine rigging components.
