National Marker N221887 Hook Eye Turnbuckle 3/8 in X 10.5 in

Product Description

The NATIONAL MARKER N221887 is a hook and eye turnbuckle designed for tensioning and adjusting the length of rigging, bracing, and tie-down assemblies. The body is hex shaped and manufactured from aluminum with a zinc finish, providing corrosion resistance in typical service environments. The hook and eye ends are steel, offering the strength needed for load-bearing applications. At 3/8 inch thread diameter and 10.5 inches in overall length, this turnbuckle suits medium-duty installations where precise tension adjustment is required. It is sold individually and weighs 0.337 pounds.

This turnbuckle is used in a range of trade and industrial applications including structural bracing, guy wire tensioning, gate hardware, fence installations, and general rigging work. The hex-shaped body allows for easy adjustment with a standard wrench, making it practical for field installation. It is appropriate for both indoor and outdoor use where a lightweight aluminum body with zinc finish provides adequate environmental resistance.
