Description
Bronze Toggle Fork & Toggle Fork represents the ultimate in dual articulation rigging hardware engineering, featuring the proven Sta-Lok Forged Turnbuckle design with precision Threaded Strap Toggles (B18/B15) at both terminations for maximum angular flexibility. This elegant assembly provides full articulation in two planes at each end, making it the ideal solution for complex rigging systems requiring multi-directional movement capability throughout the entire connection system.
Available in seven thread sizes from 1/4" to 3/4" UNF with comprehensive specifications, Bronze Toggle Fork & Toggle Fork accommodates the most demanding rigging applications where dual articulation is essential for optimal load distribution and stress elimination. The fully open dimensions range from 248mm to 580mm with closed dimensions from 172mm to 415mm, ensuring exceptional adjustment capabilities for complex rigging geometries.
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 Toggles provide full articulation in two planes at both terminations, eliminating binding and stress concentrations regardless of load direction changes throughout sailing operations. This dual articulation capability makes this turnbuckle particularly valuable for complex staying systems, and applications where load vectors vary significantly and unpredictably, ensuring smooth operation and maximum component longevity through stress elimination.
