Product Specifications

Type 302 & 304 Stainless Steel (also known as 18-8)
Used in most turnbuckle jaw studs and some toggle stampings. This material offers good corrosion resistance and high strength.

Type 316/316L Stainless Steel
Used on all swage terminals and most toggle stampings, turnbuckle bodies, and other components. This material offers better corrosion resistance with a slight trade-off in strength.

Naval Bronze
This material is used on all toggle nuts to facilitate the toggling action so that no “cold welding” of the two surfaces occurs.

Aluminum Silicon Bronze
Used in forged turnbuckle bodies and some machined turnbuckle jaw studs. Same physical properties as 300 series stainless steel. Excellent corrosion resistance.

6061 T-6 Aluminum
High strength alloy commonly used in the aerospace/marine industry, anodized for excellent corrosion resistance.

CS Johnson Pelican Hook Demo

Video demonstration of the Johnson Marine “Over Center” Pelican Hook and its safety features:

C. Sherman Johnson Company Incorporated was founded in 1958 by Curtiss S. Johnson Jr (1925 – 2005). Mr. Johnson’s love of sailing inspired him to design and manufacture stainless steel turnbuckles, fittings and marine accessories for the pleasure marine market.

We’ve always been a family-owned business, and that tradition continues today, as sons Burt and Curt III build the company together.
