C. Sherman Johnson 1/4-28 LH Snap Gate Hook Body

The C. Sherman Johnson 1/4-28 LH Snap Gate Hook Body is a service replacement for lifeline gates that use the smaller left-hand threaded connection. It is intended for owners who need to replace the hook body while retaining the compatible threaded fitting already installed on the lifeline. Matching the original thread size and direction is the critical step in choosing this replacement. Using the correct body preserves the established gate geometry without requiring a complete new hardware set.

The hook measures 3-1/2 in from the end of the body to the inside bearing point. That measurement can be used to confirm the replacement against the existing part before it is threaded into the assembly. The left-hand thread should start easily by hand when matched to the correct fitting. Any binding, cross-threading, or misalignment should be corrected before the gate is put under tension.

• Replacement body for left-hand threaded snap gate assemblies
• 1/4-28 thread for matching compatible fittings
• 3-1/2 in reference body length
• Supports repair without replacing the complete lifeline gate

Inspect the mating threads and latch components at the same time the body is replaced, since wear in those parts can affect gate security. After final assembly, the hook should close freely and remain aligned with the lifeline load. Browse more Sailing Hardware for compatible hardware and related marine rigging components.
