Ronstan Series 19 I-Beam Car - Channel Top - 19mm (3/4")

The Ronstan Series 19 I-Beam Car - Channel Top - 19mm (3/4") is a compact, precision-engineered sailing hardware component designed for small-craft rigging systems. Built for sailors, riggers, and marine technicians who demand reliable load distribution and smooth line travel, this channel-top car serves as a critical component in mainsheet and self-tacking jib traveller setups on dinghies and catamarans. Its compact 19mm footprint makes it ideal for space-constrained applications where weight savings and performance cannot be compromised.

Engineered with a stainless steel body and flared side design, the Ronstan Series 19 I-Beam Car delivers exceptional strength-to-weight ratio and corrosion resistance in saltwater environments. The angled ball bearing wheels provide smooth, low-friction operation under dynamic load conditions, ensuring responsive sail trim adjustments even under high tension. At just 0.2 lbs, this hardware component minimizes rigging weight while maintaining high load capacity—a critical advantage when every ounce affects boat performance and handling. The channel-top configuration allows secure attachment to I-beam or track systems without additional fastening hardware.

This car is ideal for racing sailors, charter operators, and dinghy class competitors who rely on precision rigging for competitive advantage. The 19mm size is purpose-built for smaller vessel applications where space efficiency and lightweight construction are mandatory specifications. Compatibility with standard I-beam track systems makes installation straightforward, and the stainless steel construction ensures years of reliable service across freshwater and offshore environments without maintenance-related performance degradation.
