Description
Bronze Fork & Sta-Lok Threaded Stud represents the ultimate in versatile rigging hardware engineering, combining the proven Sta-Lok Forged Turnbuckle design with dual termination options for maximum installation flexibility. This sophisticated assembly features a fully machined Threaded Fork End (B16) at one termination and a reusable Sta-Lok Self-Fit Stud (036) at the other, providing the perfect solution for rigging applications requiring both mechanical and wire rope connections.
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 diverse rigging requirements across various vessel sizes. The fully open dimensions range from 216mm to 504mm with closed dimensions from 140mm to 339mm, ensuring optimal adjustment capabilities for demanding sailing applications.
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 reducing wind resistance.
The reusable Sta-Lok Self-Fit Stud termination allows for easy wire rope installation and replacement without requiring specialised tools or professional rigging services, whilst the machined fork end provides secure mechanical connection to chainplates, tangs, and other rigging hardware. The high-quality polished chromium finish ensures superior corrosion protection and maintains lustrous appearance throughout extended marine exposure.
