National Marker N221846 Zinc Hook Eye Turnbuckle

Product Description

The NATIONAL MARKER N221846 is a hook and eye turnbuckle designed for tensioning and adjusting cables, rods, and wire rope assemblies in light-duty rigging and support applications. The body measures 5-1/2 inches in length with a 3/16-inch thread size and features a hex-shaped profile for easy wrench engagement during adjustment. The body is manufactured from aluminum with a zinc finish for corrosion resistance, while the hook and eye fittings are steel. At 0.059 pounds, this is a compact, lightweight fitting suited for indoor and outdoor installations where periodic tension adjustment is needed.

This turnbuckle is used in trade and general contractor applications including wire rope bracing, cable support systems, sign hanging, conduit support bracing, and light structural tie-off work. The hook-and-eye configuration allows quick attachment to anchor points without permanent fastening on one or both ends, making it practical for installations that require periodic inspection or re-tensioning. It is sold individually and is appropriate for both new construction and retrofit service work.

Key Features

• Hex-shaped aluminum body allows wrench engagement for controlled tensioning
• Zinc finish provides corrosion resistance for outdoor or damp-location use
• Steel hook and eye fittings for strength at the attachment points
• 3/16-inch thread size suits light-duty cable and rod rigging
• 5-1/2-inch body length provides meaningful take-up range for tension adjustment
• Lightweight at 0.059 pounds — minimal load addition to the supported assembly

Compatibility

Designed as a standard hook-and-eye turnbuckle for light-duty rigging, cable support, and tensioning applications requiring a 3/16-inch thread size and 5-1/2-inch body length.

Installation Notes

Installation is typically performed by electricians, riggers, or general contractors depending on the application. Before adjusting or removing a loaded turnbuckle, ensure the supported load is safely relieved or secured. Use an appropriate wrench on the hex body to thread the fittings evenly — advance both the hook and eye ends incrementally to maintain alignment and prevent cross-threading. Inspect threads and fittings for wear or corrosion before placing the assembly under tension.
