Stainless Steel Turnbuckle – Closed-Body (Inox)

This stainless steel closed-body turnbuckle is engineered for the most demanding marine and industrial conditions. Made from polished, high-grade stainless steel (marine-grade AISI 316 inox), it offers exceptional resistance to corrosion even with continuous exposure to saltwater. The closed cylindrical body gives a sleek, professional appearance while shielding the threads from dust, debris, and damage. This ensures the screw mechanism operates smoothly and the product has a long service life, even under intensive use.

With this turnbuckle, you can confidently fine-tune the tension on critical components such as yacht shrouds, safety railing cables, or structural support lines. The precise threaded mechanism of the closed body allows the fine control needed for sensitive rigging operations, without risk of self-loosening or slippage. The stainless steel construction withstands high loads without bending, making this adjuster suitable for professional applications – on sailboats, motor yachts, as well as in on-shore architectural installations.

• M5 – M6: Suitable for small sailboats and light structures. Ideal for tensioning thin wire ropes, antennas, or other delicate applications.
• M8 – M10: Perfect for mid-sized yachts (approx. 5–8 m) and general use – tightening lifelines, deck canopies, or medium-load cables.
• M12 – M14: Meant for large yachts and structures (approx. 8–12 m) where high strength and reliability are required – e.g. permanent rigging systems, architectural railings.
• M16: The largest size for extremely heavy loads and professional rigging on very large vessels (>12 m) or fixed installations (masts, major engineering projects).
