National Marker N222018 Hook Turnbuckle 5/16 X 9 Inch Zinc

Product Description

The NATIONAL MARKER N222018 is a hook-and-hook turnbuckle designed for tightening and drawing together cables, lines, and rigging assemblies. The body is extruded aluminum with a zinc-plated finish for corrosion resistance, measuring 5/16 inch by 9 inches overall. Steel wire hooks are fitted on both ends to accept rope, cable, or chain. The hex-profile body allows fast hand adjustment or wrench tightening when precise tensioning is needed. This turnbuckle is a practical hardware item used by contractors, riggers, and maintenance technicians working with tension assemblies in light-duty structural or rigging applications.

This turnbuckle fits into residential and commercial maintenance, construction staging, cable bracing, and general rigging work where controlled tension adjustment is required. The hook-and-hook configuration makes it easy to connect and disconnect without disassembling the full rigging assembly. Its compact 5/16 inch by 9 inch size suits lighter cable and wire rope runs where a manageable, low-profile tensioning device is needed.

Designed as a standard hook-and-hook turnbuckle for light-duty cable, wire rope, and line tensioning applications where a 5/16 inch body size is specified.

Installation Notes

Installation is typically performed by contractors, riggers, or maintenance technicians familiar with hardware tensioning assemblies. Before adjusting or replacing a turnbuckle under load, relieve tension from the line or cable to prevent sudden release. Use the hex body with an appropriate wrench to achieve final tension without over-extending the take-up travel. Inspect hooks and locking hardware to confirm full thread engagement before returning the assembly to service.
