G-6311 G-6313 G-6315 High tensile turnbuckle
The CONTECH® G‑63 high‑tensile turnbuckle series (types G‑6311, G‑6313, and G‑6315) consists of open‑body rigging screws designed for the tensioning and adjustment of wire ropes and steel cables in rigging, and securing applications. Each type within the G‑63 series is available with different end configurations to suit a wide range of connection requirements:
The Working Load Limit (WLL) of the G‑63 turnbuckles must only be applied in a straight‑line pull. The products are not designed for side loading, bending forces, or dynamic misalignment, and such conditions may lead to premature wear, deformation, or failure. Overloading is strictly prohibited and will compromise both safety and product integrity.
These turnbuckles are intended solely for static tensioning applications, such as pre‑tensioning of wires or maintaining load position—not for shock loading or lifting operations.
To ensure continued safe operation, it is mandatory that G‑63 turnbuckles are inspected at regular intervals. Inspections must be carried out in accordance with the applicable safety standards and regulations of the country of use. Regular inspection is essential because products in service may be affected by:
Any turnbuckle showing visible deformation, cracks, excessive wear, or damaged threads must be removed from service immediately.
