Description
Bronze Toggle & Sta-Lok Threaded Stud represents the ultimate in sophisticated rigging hardware engineering, combining the proven Sta-Lok Forged Turnbuckle design with advanced articulation and reusable wire termination capabilities. This elegant assembly features a precision Threaded Strap Toggle (B18) at one end and a reusable Sta-Lok Self-Fit Stud (036) at the other, providing the ideal solution for complex rigging systems requiring both full two-plane articulation and convenient wire rope installation flexibility.
Available across comprehensive wire sizes from 3mm to 12mm (metric) and 1/8" to 1/2" (imperial) with corresponding UNF thread specifications, this turnbuckle accommodates demanding rigging applications where both angular movement and wire termination convenience are essential. The fully open dimensions range from 231mm to 521mm with closed dimensions from 155mm to 353mm, ensuring optimal adjustment capabilities for diverse sailing 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 complex load vectors associated with articulating connections.
The precision Threaded Strap Toggle provides full articulation in two planes, eliminating binding and stress concentrations during load direction changes, whilst the reusable Sta-Lok Self-Fit Stud enables easy wire rope installation and replacement without requiring specialised tools or professional rigging services. This combination makes this turnbuckle particularly valuable for standing rigging systems, adjustable stays, and applications where both angular flexibility and maintenance convenience are paramount.
