The Ronstan RF1054 Saddle 18mm Clearance is a heavy-duty marine-grade stainless steel rope and cable guide designed for secure routing of larger diameter rope, wire, hose, or electrical conduit on boats.

With its wide 18mm internal clearance, this saddle is ideal for high-load and larger rigging applications, making it perfect for lifelines, control lines, and hose management systems.

Constructed from forged 316 stainless steel, the RF1054 delivers outstanding resistance to corrosion, pitting, and fatigue—ensuring long-term reliability in harsh saltwater conditions common around New Zealand.

Its low-profile, polished finish reduces snagging and line wear while maintaining a clean, professional deck layout. This makes it a go-to choice for yachts, trailer boats, and workboats requiring strong and durable deck fittings.

Why Choose the Ronstan RF1054? 

For New Zealand boat owners, managing larger diameter lines and systems requires fittings that can handle higher loads without compromising deck layout.

The RF1054 stands out because it offers:

• Maximum clearance in a compact saddle design
• Excellent strength-to-weight ratio
• Reliable performance in saltwater and UV-heavy environments

Compared to saddles with eyes (RF1056/57/58), this model is best when you only need a clean, strong guide without an attachment point, keeping installations simple and uncluttered.
