Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N221-838 is a stainless steel eye-eye turnbuckle designed for tightening and drawing together lines and cables under load. The body measures 0.25 inches in diameter with a 7.5-inch body length and carries a safe working load of 110 pounds. Constructed from stainless steel with passivated eyes for added corrosion resistance, this turnbuckle is non-magnetic and built to withstand atmospheric corrosion in demanding environments. The hex-shaped body allows adjustment by hand or with a standard wrench, making field tensioning straightforward for marine riggers, electricians securing cable runs, or general contractors working on outdoor structures.

This turnbuckle is suited for marine rigging, cable railings, guy wire tensioning, and other outdoor applications where corrosion resistance is a primary concern. The eye-eye configuration accepts shackles, hooks, or fixed anchor points at both ends, giving installers flexibility across a range of tensioning tasks. Its non-magnetic stainless steel construction makes it appropriate for environments where magnetic interference must be avoided. Sold in bulk packaging, this part is a practical stock item for marine service shops and contractors who regularly work with cable and line systems.

Compatibility

Designed as a standard eye-eye turnbuckle for marine rigging, cable tensioning, and general outdoor hardware applications requiring a 0.25-inch diameter stainless steel fitting.

Installation Notes

Installation is typically performed by marine riggers, electricians, or general contractors familiar with cable tensioning hardware. Before adjusting or replacing a turnbuckle under load, relieve tension on the cable or line system first. Use a properly sized wrench on the hex body to achieve final tension without over-rotating, which can reduce thread engagement below safe limits. Inspect threads and eyes for damage before placing the fitting in service.
