Description
Bronze Toggle & Fork represents the ultimate in versatile rigging hardware engineering, combining the proven Sta-Lok Forged Turnbuckle design with dual articulation capabilities through sophisticated toggle and fork terminations. This elegant assembly features a precision Threaded Strap Toggle (B18) at one end and a Threaded Fork End (B17) at the other, providing the ideal solution for complex rigging systems requiring both multi-directional articulation and secure mechanical connection.
Available in seven thread sizes from 1/4" to 3/4" UNF with comprehensive specifications, Bronze Toggle & Fork accommodates demanding rigging applications where both angular flexibility and mechanical attachment are essential. The fully open dimensions range from 238mm to 566mm with closed dimensions from 162mm to 398mm, whilst toggle and fork specifications provide precise fit for diverse rigging configurations and load requirements.
The advanced Sta-Lok Forged Turnbuckle design exceeds the breaking load of today's high-strength compacted strand wire ropes through superior forging and machining processes utilising high-strength bronze alloy construction. The aerodynamic design philosophy creates one of the strongest and most elegant bronze turnbuckles available on the world market today, optimising strength-to-weight ratios whilst accommodating the complex load vectors associated with dual articulation systems.
The precision Threaded Strap Toggle provides full articulation in two planes, eliminating binding and stress concentrations during load direction changes, whilst the Threaded Fork End ensures secure mechanical connection to chainplates, tangs, and rigging hardware. This combination makes Bronze Toggle & Fork particularly valuable for running rigging systems, adjustable stays, and complex applications where load vectors vary significantly throughout sailing operations.
