LGRIG® Galvanized Hook & Hook Turnbuckle US Fed Spec HG-223, also known as Forged Turnbuckle Hook-Hook HG-223 US Fed Spec, is a very common steel turnbuckle throughout the rigging industry.
Galvanized turnbuckles provide an efficient solution for tensioning, loosening, and removing chain and rope load lines, particularly in applications involving wire rope or cable adjustment.
Constructed from hot-dip galvanized forged steel for enhanced durability, corrosion resistance, and weather adaptability, they consist of a central body with two end fittings—available in eye, jaw, or hook configurations—designed exclusively for straight in-line pulling to ensure safety and performance.
With a design factor of 5:1, they must only be loaded within their specified working load limit, applying force centrally to eye fittings or the bowl of hooks to avoid side loading or contact with threaded shanks.
These turnbuckles are essential in marine, rigging, and architectural industries, offering versatile types (jaw-jaw, eye-eye, hook-hook, eye-jaw, hook-eye) for various tensioning needs.
The hook-and-hook design, for instance, enables quick attachment and detachment ideal for temporary setups like tents, tarps, or rapid cable adjustments, while maintaining reliable performance across outdoor and demanding environments.
