Description
The Supajust Fork & Sta-Lok is a premium open-body turnbuckle that combines a fixed fork connection with a self-fit Sta-Lok stud for versatile rigging solutions. The body is precision-machined from polished 316 stainless steel, delivering excellent corrosion resistance and strength. Internally, threaded bronze inserts are permanently sealed into each end to prevent galling and ensure smooth adjustment even under high loads.
One end is fitted with a machined fork, offering a solid, fixed connection point to chainplates or structural tangs. The other end is terminated with a Sta-Lok self-fit stud, allowing for tool-free assembly without swaging. Together, this configuration supports secure connections while simplifying installation. The open-body design allows visual inspection of thread engagement during tensioning. Once proper load is achieved, traditional split pins can be employed for positive locking and stability in all conditions.
Supajust Fork & Sta-Lok is available in a spectrum of thread sizes and compatible with a wide range of wire diameters, making it ideal for demanding marine, architectural, or rigging applications.
