Eye and Eye Turnbuckles are dro forged for added strength compared to a machined or precision cast turnbuckle. The dro forged process adds strength while the Type 316 stainless steel offers the highest level of corrosion protection. The turnbuckle eyes are elongated, similar to the Galvanized Eye and Eye Turnbuckle, for less stress on the eye and for easier attachment of other hardware. Our eye turnbuckles are US type and meet dimensions of ASTM specification F1145-92 Type 1, Class H. If you need assistance with Turnbuckles or other Rigging Hardware
