C. Sherman Johnson 3/8-24 T-Style Tubular Turnbuckle

The C. Sherman Johnson 3/8-24 T-Style Tubular Turnbuckle is designed for 1/4 in standing-rigging wire and uses an integral toggle jaw at the attachment end. That built-in articulation helps the terminal align with normal rig movement while avoiding the added length and hardware of a separate toggle. The machine-swage configuration creates a permanent wire termination for a clean, conventional rigging setup. Its open adjustment area also makes thread engagement visible when the rig is tuned.

The turnbuckle adjusts from 9-1/2 in closed to 13-3/4 in open when measured from pin to pin. A 5-5/8 in body carries the 3/8-24 thread, and the jaw uses a 3/8 in pin. Forged silicon bronze is paired with 316 stainless ends to limit galling at the threaded interface. The published breaking strength is 7,000 lb, providing a reference for matching the fitting to compatible wire and surrounding hardware.

• Integral toggle jaw reduces the need for an added rigging toggle
• Machine-swage terminal for 1/4 in wire
• 9-1/2 in closed and 13-3/4 in open pin-to-pin length
• 5-5/8 in body with 3/8 in jaw pin

Confirm the available adjustment, pin diameter, and wire termination before replacing an existing turnbuckle or building a new stay. Keeping the threads and attachment pin accessible makes future tuning and inspection easier. Browse more Sailing Hardware for compatible hardware and related marine rigging components.
