Ronstan Spinnaker Pole Ring - Curved Base - 30mm (1-3/16") ID

The Ronstan Spinnaker Pole Ring with curved base and 30mm inner diameter is a precision rigging component engineered for marine and automotive applications requiring secure, load-bearing attachment points. Built for professionals who demand reliability in high-stress environments, this ring serves as an essential connector in systems where equipment stability and alignment are non-negotiable—whether on the water or in specialized vehicle modification setups where custom hardware integration is critical.

The 30mm (1-3/16 inch) inner diameter opening accommodates standard poles and shafts with precise tolerances, while the curved base design distributes loads evenly and prevents rotation under operational stress. Ronstan's engineering emphasizes durability and corrosion resistance through advanced material selection, ensuring this ring maintains structural integrity across varying environmental conditions. The compact footprint—measuring 2 x 1 x 2 inches and weighing just 0.1 lbs—allows for seamless integration into tight spaces without compromising weight distribution or system balance, a critical consideration in both marine rigging and automotive modification applications.

Mechanics and fabricators installing custom accessory mounting systems, reinforced tie-down points, or modular equipment racks will find this ring invaluable for creating repeatable, professional-grade attachment solutions. The curved base prevents binding and ensures smooth operation even under dynamic loading conditions. Compatibility extends across any 30mm diameter pole or shaft application, making it a versatile choice for both OEM upgrades and aftermarket system builds where precision hardware elevates overall system reliability.
