C. Sherman Johnson 5/16-24 LH Snap Gate Hook Body

The C. Sherman Johnson 5/16-24 LH Snap Gate Hook Body is a replacement body for lifeline gate assemblies that already use the matching left-hand thread. It allows an owner to replace a worn or damaged hook body without discarding compatible threaded hardware elsewhere in the gate. The manufacturer’s key instruction is to match the existing thread size and direction before ordering. That makes this part most useful for service work where the original gate dimensions are already known.

The body measures 3-1/2 in from its threaded end to the inside bearing point of the hook. This dimension helps compare the replacement against the removed part before the lifeline is reassembled. The left-hand thread is intentional and should not be forced onto a right-hand mating fitting. Once installed, the hook body should articulate and close cleanly without side load from a misaligned gate.

• Replacement hook body for existing lifeline gate hardware
• 5/16-24 left-hand thread
• 3-1/2 in body-to-bearing-point length
• Useful for repairing a gate without replacing every fitting

Compare the old and new parts side by side before tensioning the lifeline so thread direction and overall geometry are confirmed. Gate security also depends on the condition of the mating threaded fitting and the rest of the latch assembly.
