National Marker N221952 Hook Eye Turnbuckle Stainless Steel

Product Description

The NATIONAL MARKER N221952 is a hook eye turnbuckle constructed of stainless steel with an aluminum hex-shaped body, designed for tightening or drawing together lines, cables, and rigging. The 0.25-inch diameter by 7.5-inch length configuration suits a range of tensioning tasks where corrosion resistance is a priority. The passivated eyes deliver superior resistance to atmospheric corrosion, and the nonmagnetic construction makes this turnbuckle appropriate for sensitive environments. The hex-shaped body allows adjustment by hand or with a standard wrench, reducing installation time in the field.

This turnbuckle is well suited for marine rigging, outdoor cable management, and coastal or high-humidity environments where standard steel hardware would corrode prematurely. The combination of a stainless steel hook and eye with a corrosion-resistant aluminum body makes it a dependable choice for both permanent installations and temporary tensioning applications. It is sold individually and ships boxed loose.

Key Features

• Passivated stainless steel eyes for superior atmospheric corrosion resistance
• Nonmagnetic construction suitable for sensitive or marine environments
• Hex-shaped aluminum body allows hand or wrench adjustment
• Hook and eye configuration for versatile line and cable connections
• Sized at 0.25 inches x 7.5 inches for a wide range of tensioning tasks

Compatibility

Designed as an OEM-style replacement or direct-use turnbuckle for marine, outdoor rigging, and cable tensioning applications requiring corrosion-resistant hardware.

Installation Notes

Turnbuckles of this type are typically installed by rigging professionals, marine technicians, or general contractors working with cable and line tensioning systems. Before installation, ensure all connected lines or cables are de-tensioned and secure. Use a wrench on the hex body for final tensioning; do not over-torque beyond the rated load of the connected hardware. Inspect passivated surfaces periodically in high-salinity or outdoor environments to confirm corrosion resistance is maintained.
