Key Features:
- Closed-Body Pipe Design: Unlike open-body turnbuckles, the solid pipe construction provides enhanced resistance to compression, torsion, and environmental wear—ideal for permanent or high-load installations.
- Eye-and-Eye Configuration: Allows for secure, swivel-free attachment to cables, rods, chains, or anchor points using shackles or clevis pins.
- Forged Carbon Steel Construction: Heat-treated for maximum tensile strength and fatigue resistance.
- Hot-Dip Galvanized Finish: Offers excellent corrosion protection for outdoor, marine, or industrial environments.
- DIN 1478 Compliance: Meets strict European dimensional and performance standards for structural turnbuckles.
Common Applications:
- Structural bracing in steel buildings and towers
- Guy wire tensioning for antennas, masts, and signage
- Bridge cable adjustments and suspension systems
- Industrial rigging and permanent load-securing setups
- Architectural tensioning systems (e.g., cable railings, canopies)
Safety & Installation Guidelines:
- Not intended for overhead lifting of personnel—designed for static or semi-static tensioning only.
- Always verify the Working Load Limit (WLL) and never exceed it.
- Ensure eyes are fully engaged and not subjected to side-loading or bending forces.
- Inspect regularly for thread wear, corrosion, or body deformation—replace if compromised.
Engineered to European standards and built for strength—the DIN 1478 Closed-Body Pipe Turnbuckle delivers reliable, long-lasting performance in the most demanding tensioning applications.
