Ronstan Series 25 T-Track - Spinnaker Pole - Composite Slide & Stop - 102mm (4")

The Ronstan Series 25 T-Track Spinnaker Pole with Composite Slide & Stop is a precision-engineered marine hardware component designed for sailors and boat owners who demand reliability in demanding conditions. This 102mm (4-inch) T-track system functions as an essential control mechanism for spinnaker poles, enabling smooth, repeatable adjustments while maintaining structural integrity under load. Built by Ronstan, a trusted manufacturer in marine rigging hardware, this product addresses the need for durable, low-maintenance pole control systems that can withstand saltwater exposure and constant operational cycling.

The composite slide design eliminates friction-related wear that degrades traditional metal-on-metal systems, extending service life while reducing maintenance intervals. The integrated stop mechanism prevents over-travel, protecting the pole and attached rigging from damage during aggressive sail transitions. At just 0.5 lbs, the lightweight construction minimizes weight aloft—a critical factor in sailing performance where reduced inertia improves response and stability. The T-track profile ensures positive, indexed positioning, allowing crew members to make quick, confident adjustments without fumbling or losing control during maneuvers.

Sailors operating spinnaker poles in cruising or racing applications will find this component essential for controlling pole angle and fore-aft position with precision. The composite construction resists corrosion, making it ideal for saltwater and coastal environments where traditional hardware deteriorates rapidly. Installation integrates seamlessly into existing Series 25 T-track systems (MPN RC72544), ensuring compatibility with complementary Ronstan rigging components and allowing for modular system expansion as your boat's needs evolve.
