Professional Marine Grade Tensioning Hardware
Engineered for extreme saltwater environments, our AISI 316 Stainless Steel Closed Body Turnbuckles offer a streamlined, snag-free alternative to traditional open-frame rigging. The precision-machined pipe body fully encases the threads, protecting them from damage and debris while providing a modern architectural aesthetic.
- Maximum Corrosion Resistance: Molybdenum-enriched 316 alloy outperforms standard 304 steel in chloride-heavy coastal conditions.
- Snag-Free Design: The closed-body construction eliminates external sharp points, making it ideal for sailboat lifelines and architectural sun shades.
- Secure Jaw Fittings: Dual jaw-and-jaw ends feature removable bolts and security ring pins for fail-safe attachment to fixed eyelets and deck toggles.
- High-Lustre Finish: Mirror-polished surface provides superior reflectivity and prevents salt accumulation.
Ideal for yacht rigging, balustrade systems, and high-tension shade sail applications.
Frequently Asked Questions
- Will the threads in this turnbuckle seize or gall in saltwater?
- No, our 316 Stainless Steel is molybdenum-enriched for superior corrosion resistance. Furthermore, the closed-body 'pipe' design protects the internal threads from salt spray and debris accumulation, significantly reducing the risk of seizing compared to open-frame models.
- Is this turnbuckle rated for overhead lifting?
- These turnbuckles are designed for tensioning applications such as rigging, lifelines, and sun shades. While they have high Safe Working Loads (up to 300kg for M20), they are not intended for structural overhead lifting; always refer to the SWL table provided for specific sizing.
- Can I use these for outdoor deck balustrades without it snagging clothing?
- Yes. The primary engineering advantage of the closed-body design is its smooth, cylindrical profile. Unlike open-body turnbuckles, there are no exposed sharp threads or corners, making it the safest choice for residential balustrades and high-traffic areas on vessels.
