The Seldén Fork-Fork Double Toggle (also known as Jaw-Jaw or Double Fork Toggle) is a high-quality stainless steel rigging component essential for secure and articulated connections in sailboat standing rigging, particularly with Furlex jib furling systems.
Precision-machined from marine-grade AISI 316 stainless steel, it delivers outstanding corrosion resistance, strength, and longevity in harsh saltwater environments.
Primary Purpose
This double fork (jaw-jaw) toggle provides full articulation in two planes, allowing perfect alignment with the load direction. It prevents bending fatigue on wire terminals, reduces stress on connections, and ensures smooth movement—critical at the lower end of forestays, shrouds, or between furling units and deck attachments. It's the standard toggle supplied with many Seldén Furlex kits and is recommended for connecting eye terminals, extension links, or rigging screws to chainplates/padeyes.
Key Features & Benefits
- Fork-to-fork (double jaw) design — Both ends feature open jaws (clevis forks) with cross pins for secure, pivoting connections.
- Enables multi-directional articulation to accommodate rig movement and prevent undue stress or wire fatigue.
- Manufactured to Seldén's exacting standards for precise fit and load distribution.
- Available in 9 sizes to match common wire diameters (from 4 mm to 16 mm), with variations in pin diameter, length, fork width, and overall dimensions.
