C. Sherman Johnson 5/16-24 T-Style Tubular Turnbuckle

The C. Sherman Johnson 5/16-24 T-Style Tubular Turnbuckle combines a traditional rigging layout with an integral toggle jaw for easier alignment at the attachment point. It is configured for 3/16 in wire and uses a machine-swage end for a permanent terminal connection. The built-in toggle helps the fitting follow normal rig movement without adding a separate toggle between the turnbuckle and chainplate. This makes it a practical choice for compact standing-rigging installations that still need useful adjustment range.

The 5/16-24 threaded assembly measures 9 in pin-to-pin when closed and extends to 12-3/4 in when opened. Its body length is 5-1/8 in, and the jaw accepts a 5/16 in pin. The forged silicon bronze body works with 316 stainless ends to create a durable threaded combination with reduced tendency to gall. The manufacturer rates the fitting to a 4,000 lb breaking strength for system-planning purposes.

• T-style toggle jaw is integrated into the terminal
• Machine-swage end is sized for 3/16 in wire
• 9 in closed and 12-3/4 in open pin-to-pin range
• 5-1/8 in body with 5/16 in attachment pin

Match the fitting to the existing wire, chainplate, and terminal dimensions before installation so the articulation and adjustment range are correct. Routine inspection should include the exposed threads, jaw pin, and swaged connection as part of the standing rig.
