C. Sherman Johnson 1/8 in Jaw-to-Swage Turnbuckle

The C. Sherman Johnson 1/8 in Jaw-to-Swage Turnbuckle provides a compact traditional adjustment point for smaller standing-rigging wire. One end uses a jaw for a pinned connection, while the opposite end is swaged directly onto 1/8 in wire. This arrangement keeps the connection simple and leaves the open threaded body accessible during final tuning. It is a straightforward replacement option where the existing rig already uses the same wire and pin dimensions.

The forged silicon bronze body is paired with T-316 stainless terminal ends to create a durable threaded combination. The jaw accepts a 1/4 in pin, and the turnbuckle provides 3 in of adjustment. That travel gives the installer room to set final stay tension after the wire length has been established. The swage terminal should be installed with tooling and procedures appropriate to the wire and fitting.

• Jaw and machine-swage terminal in one adjustable fitting
• Designed for 1/8 in wire
• 1/4 in jaw pin for the attachment end
• Three inches of available adjustment

Measure the existing installation carefully before cutting wire because the finished swage cannot be repositioned later. After tuning, inspect the exposed threads and attachment pin and make sure adequate thread engagement remains in the body.
