Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N177-493 is a galvanized hook and eye turnbuckle designed for applications requiring maximum corrosion protection and structural strength. Sized at 3/8 inch body diameter and 6 inches in length, this turnbuckle carries a safe working load of 700 pounds. The end fittings are heat treated for added tensile strength, and the body features hex heads that allow fast, easy adjustment without special tooling.

Always de-tension or unload the assembly before adjusting or replacing a turnbuckle. Verify that the safe working load of 700 pounds is not exceeded for the intended application, accounting for dynamic and shock loads. Inspect threads and end fittings for damage before putting the assembly into service.
