Custom Aluminium Alloy Turnbuckle – Any Length & Thread Pitch | OEM Bulk Orders Available
The Dual-Hook Aluminum Alloy Turnbuckle is a high-performance, lightweight tensioning device designed for applications where strength-to-weight ratio and corrosion resistance are critical.
Key Features
✅ Corrosion-Resistant – Anodized or marine-grade coatings for saltwater environments
✅ Precision Adjustment – Left & right-hand threaded rods for fine-tuning tension
✅ Safety Locking – Integrated lock nuts or wire holes prevent accidental loosening
✅ Smooth Operation – Self-lubricating threads reduce galling and wear
✅ Customizable – Available in different finishes, lengths, and thread sizes
Working Principle
The turnbuckle operates via:
Opposing Threads – One hook has right-hand threads, the other left-hand threads
Central Barrel – Rotating the barrel shortens or lengthens the assembly
Locking Mechanism – Lock nuts or wire holes secure the adjustment
This provides:
✔ Micro-adjustment capability (±2-6 inches typically)
✔ Even load distribution (no single-point stress)
✔ Vibration resistance (when properly locked)
Applications
Marine Rigging – Sailboat stays, lifelines, and dock lines
Industrial Machinery – Belt tensioners, conveyor systems
Cooperate with lead wire stick wire implement, traction and tighten up lead wire. 2.Tightening range is big, practicability strong.
High Quality Model SJS Double Hook Turnbuckle is used in power transmission construction, telecommunications engineering, tighten the wire. Apply to tightening conductor,steel wire rope or steel standed wire on installing stay wire and replacing insulator string.
