National Marker N221762 Eye Eye Turnbuckle 3/8 X 10.5 Inch

Product Description

The NATIONAL MARKER N221762 is a 3/8-inch by 10-1/2-inch eye-and-eye turnbuckle designed for tensioning and adjusting the length of cables, rods, and wire rope assemblies. The body is hex-shaped aluminum with a zinc finish, providing corrosion resistance in light-duty rigging applications. The eyes are steel. This turnbuckle is sold individually and is used by riggers, contractors, and maintenance professionals who need a reliable mechanical tensioner for structural, utility, or support-line work.

This turnbuckle is suited for residential and light commercial rigging tasks such as bracing, guy-wire tensioning, and support-line adjustment. The eye-and-eye configuration allows connection to hooks, shackles, cables, or anchors at both ends. The hex body profile allows a wrench to hold the body while the eyes are adjusted, making single-person installation more manageable. It fits applications where a compact, adjustable tensioner is needed in a corrosion-resistant form.

Key Features

• Eye-and-eye configuration for versatile end connections at both terminals
• Hex-shaped body allows wrench engagement for controlled tensioning without body rotation
• Aluminum body with zinc finish for corrosion resistance in exposed or outdoor environments
• Steel eyes provide added strength at the connection points
• Sold individually, one per unit of measure

Compatibility

Designed as a standard eye-and-eye turnbuckle replacement or new-install component for light-duty rigging, bracing, and tensioning applications requiring a 3/8-inch by 10-1/2-inch body size.

Installation Notes

Installation is typically performed by rigging, construction, or maintenance trades. Ensure all connected hardware — shackles, hooks, or anchors — is rated for the intended load before tensioning. Tighten each eye evenly and apply a locking device or safety wire to the body after tensioning to prevent loosening from vibration. Never exceed the rated working load limit for the turnbuckle or any attached hardware.
