C. Sherman Johnson 26-412 Closed Body Lifeline Turnbuckle with Hand Crimp Terminal for 1/8" Wire

The C. Sherman Johnson 26-412 is a closed-body tubular lifeline turnbuckle featuring a toggle jaw on one end and a hand crimp terminal on the other, sized for 1/8" wire. Designed for sailboat lifeline systems, this turnbuckle installs at the bow or stern rail to tension the longest run of lifeline wire. The streamlined tubular body eliminates exposed threads and snag points, keeping lines and sails clear of cotter pins and sharp edges.

The toggle jaw end provides an increased range of articulation compared to a fixed jaw, accommodating slight misalignment between fittings during tensioning and under load. Locking is achieved with check nuts on either side of the turnbuckle body, removing the need for cotter pins entirely. The center cross-hole allows easy tension adjustment by hand or with a marlinspike.

The hand crimp threaded terminal is constructed from 316 stainless steel and is matched to 1/8" wire diameter. When properly installed using appropriate hand crimping tools, a hand crimp fitting achieves approximately 65–70% of the breaking strength of 7x7 stainless steel wire — adequate for lifeline applications. This fitting is intended for lifeline use only and should not be used for standing rigging or other high-load applications.
