US Cargo Control Jaw and Jaw Turnbuckles are hot dip galvanized for durability and weather resistance. Our heavy duty turnbuckles are made for in-line or straight pull applications only. This galvanized turnbuckle features a jaw on each end which is fitted with a nut and bolt. Turnbuckles are measured by the diameter of the bolt and the length of the opening of the turnbuckle body. The overall length of this turnbuckle will be longer than the stated length, as that only pertains to the opening of the turnbuckle body. This turnbuckle is designed to ASTM F1145 specifications.
