Ronstan Screw-On Plastic Nylon Bush - Stainless Steel Lined - 7mm (9/32") ID x 14mm (9/16") Deep

The Ronstan Screw-On Plastic Nylon Bush with Stainless Steel Lined construction is a precision fairlead designed for marine, rigging, and control-line applications where deflection and angle correction are essential. This compact 7mm ID x 14mm deep bush serves as a simple yet economical solution for managing rope and cable routing on vessels, racing dinghies, and tactical equipment platforms. Fairleads of this type prevent chafing, reduce friction, and ensure proper lead angles for sheets, halyards, and other running rigging systems.

Engineered from durable nylon with a stainless steel internal liner, this bush combines lightweight construction with corrosion resistance and wear durability. The stainless steel lining protects against degradation from saltwater exposure and abrasive rope contact, while the nylon body remains non-corrosive and reduces weight compared to all-metal alternatives. The screw-on design allows quick installation and removal without special tools, making it ideal for field adjustments or maintenance. The 7mm inner diameter accommodates standard control line diameters commonly found in marine and tactical applications, while the 14mm depth provides adequate bearing surface for smooth line movement.

This fairlead is particularly valued by sailors, riggers, and equipment specialists who demand reliability in harsh environments. Installation is straightforward—simply screw onto the appropriate mounting point where line deflection or lead angle correction is needed. Ronstan's reputation for marine-grade hardware ensures this bush meets stringent standards for safety and longevity. Whether outfitting a racing yacht, commercial vessel, or tactical gear system, this versatile component delivers consistent performance and protection for your critical control lines.
