Description
The NATIONAL MFG/SPECTRUM BRANDS HHI N177-402 is a galvanized eye-and-eye turnbuckle designed for applications where corrosion resistance and load-bearing strength are critical. Built to a 0.5-inch body diameter and 6-inch take-up length, it carries a safe working load of 1,800 pounds. End fittings are heat treated for added tensile strength, and the body features hex heads that allow fast, tool-assisted adjustment in the field. It meets Federal Specification FF-T-791B, Type 1, Form 1, Class 4. This hardware is suited for marine, industrial, and construction environments where galvanized protection is required against moisture and harsh atmospheric conditions.
This turnbuckle is a standard choice for tensioning wire rope, cable, rod, or strap assemblies in marine rigging, structural bracing, fencing, and construction tie-down applications. The eye-and-eye configuration accepts clevis pins, shackles, or hooks on both ends, giving riggers and contractors flexibility in how they connect to anchor points or load lines. It is sold in a package quantity of 10 units, making it practical for contractors or service teams stocking hardware for multiple installations.
Key Features
- Galvanized finish provides maximum corrosion protection for marine, industrial, and construction use
- Safe working load of 1,800 pounds per Federal Specification FF-T-791B, Type 1, Form 1, Class 4
- Heat-treated end fittings for increased tensile strength and fatigue resistance
- Hex-head body design allows fast, wrench-assisted adjustment without specialized tools
- Eye-and-eye configuration is compatible with standard pins, shackles, and rigging hardware
- Sold in a 10-unit bulk pack suitable for project or inventory stocking
Compatibility
Designed for general-purpose rigging and tensioning applications in marine, industrial, and construction settings where Federal Specification FF-T-791B compliance is required. No specific OEM or proprietary system compatibility is listed for this part.
Installation Notes
Installation is typically performed by riggers, ironworkers, marine technicians, or construction tradespeople familiar with load-bearing hardware. Always verify that the connected hardware shackles, wire rope clips, or pins is rated at or above the 1,800-pound safe working load before putting the assembly into service. Use the hex-head body with an appropriate wrench to tension evenly; do not overtighten beyond the rated take-up length. Inspect galvanized coating and end fittings for cracks or corrosion before each use in load-bearing applications.
