The NATIONAL MARKER N221838 is a stainless steel eye-eye turnbuckle designed for tightening and drawing together lines, cables, and rigging assemblies. The body is hex-shaped, allowing adjustment by hand or with a standard wrench. Eyes are passivated for superior corrosion resistance, and the overall construction is nonmagnetic. The body is made of aluminum with stainless steel hardware, making this turnbuckle well suited for marine environments and other outdoor applications where exposure to moisture and atmospheric corrosion is a primary concern. This fitting is sold individually and is a practical choice for rigging, tensioning, and cable management tasks performed by contractors, marine technicians, and maintenance professionals.
This turnbuckle is intended for marine and general outdoor rigging applications where corrosion resistance is essential. The passivated stainless steel eyes and aluminum body resist atmospheric corrosion without the interference concerns associated with magnetic hardware. Typical installations include boat rigging, outdoor cable tensioning, fence bracing, and structural tie-back assemblies. The 1/4 inch diameter and 7-1/2 inch overall length make it suitable for light to medium-duty tensioning tasks in both residential and commercial settings.
Designed as an OEM-style replacement and standard fitment for 1/4 inch eye-eye turnbuckle applications in marine and outdoor rigging systems.
Installation is typically performed by rigging professionals, marine technicians, or general contractors. Before servicing or replacing a turnbuckle in a load-bearing assembly, relieve all tension from the line or cable. Do not exceed the rated working load limit for the fastener diameter. Inspect threads and eyes for wear or corrosion before placing the assembly back into service.
