Product Details

The C. Sherman Johnson 27-316 is a classic open body lifeline turnbuckle engineered specifically for sailboat lifeline applications. Combining a forged silicon bronze body with T-316 stainless steel ends, this turnbuckle delivers an ideal balance of corrosion resistance, strength, and long-term reliability in demanding marine environments.

The dissimilar metal construction is a key engineering advantage: the bronze turnbuckle body prevents galling against the stainless steel studs and threaded terminal — a common problem when stainless contacts stainless under load. The T-316 stainless steel toggle jaw provides a wide range of articulation to improve lifeline alignment and reduce stress at the terminal point.

The hand crimp threaded terminal end is designed for straightforward installation using a proper hand crimping tool, making this fitting suitable for DIY rigging by boat owners as well as professional riggers. A unique slotted locking design with wrap-around rings fits through holes in the studs for positive, secure locking without the need for additional lock nuts.

Key Features:

  • Classic open body turnbuckle design for lifeline use
  • Forged silicon bronze body resists galling against stainless steel studs
  • T-316 stainless steel toggle jaw and threaded terminal studs for superior marine corrosion resistance
  • Toggle jaw allows increased range of motion and improved lifeline alignment
  • Positive locking via slotted body with wrap-around rings through stud holes
  • Hand crimp terminal end — compatible with standard hand crimping tools
  • Includes clevis pins and cotter rings

Specifications:

  • Wire Size: 3/16"
  • Pin Size: 1/4"
  • Adjustment Range: 2-3/4" – 3"
  • Body Material: Forged silicon bronze
  • End Material: T-316 stainless steel
  • Made in USA

Important Note: Hand crimp fittings, when properly installed, provide approximately 65–70% of the breaking strength of 7×7 stainless steel wire. These fittings are suitable for lifeline applications only and should not be used for standing rigging or other high-load purposes. Always follow the manufacturer's crimping tool instructions for a safe installation.

The website was easy to navigate. I found the product easy peasy. Placed order and my order was delivered within days not weeks. I would order again from them if I ever need shocks again.

The turbo (s475sx-e) has been my best purchase this year. The order was placed at the end of the workday and Thmotorsports shipped it the very next morning, also the box arrived in magnificent condition, the turbo was picture perfect without a blemish. Thmotorsports was the most affordable out of all ten sites that were considered, with top notch shipping. I have to say Thmotorsports was the best choice for my genuine part.
