This U.S. Type turnbuckle design meets the dimensions of ASTM F1145-92 Type 1, Class H.
The eye end provides a secure, permanent attachment point (ideal for bolting to anchor points), while the hook end enables tool-free, rapid connection and release. This design makes the Hook and Eye turnbuckle a versatile choice for applications that require both stability and flexibility.
Turnbuckles are used to apply tension for support or suspension, and can be adjusted by simply rotating the body in either direction.
Made of 316 stainless steel construction offers excellent corrosion resistance and overall versatility, while the polished finish provides a smooth, shiny surface.
One end is right handed and the opposite end is left handed. You create tension by simply rotating the turnbuckle centre body.
