National Mfg N177-394 Galvanized Eye Eye Turnbuckle 3/8x6

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N177-394 is a galvanized eye-and-eye turnbuckle designed for applications that demand reliable tension adjustment and strong corrosion resistance. Sized at 3/8 inch body diameter and 6 inches in length, this turnbuckle carries a safe working load of 1,040 pounds. The end fittings are heat treated for added strength, and the body features hex heads to allow fast, easy adjustment with standard hand tools. It is sold in a pack of 5 units and meets Federal Specification FF-T-791B, Type 1, Form 1, Class 4, confirming it is built to a recognized performance standard for load-bearing hardware.

This turnbuckle is suited for marine, industrial, and construction environments where maximum corrosion protection and structural integrity are priorities. Typical uses include tensioning wire rope, cable, or rod assemblies in rigging systems, bracing frameworks, and tie-down applications. The hot-dip galvanized finish makes it a practical choice for outdoor and coastal installations where exposure to moisture and salt air accelerates corrosion on unprotected hardware. Each unit in the 5-pack is identical, making the quantity useful for multi-point rigging jobs or project stock.

Installation Notes

Turnbuckles of this type are typically installed by riggers, ironworkers, or general contractors working within applicable load and rigging codes. Always de-tension or remove the load from the assembly before adjusting or replacing a turnbuckle. Ensure both eye fittings are properly seated and secured to their anchor points before applying tension. Do not exceed the rated safe working load of 1,040 pounds, and inspect the hardware regularly for signs of wear, deformation, or coating failure.
