Closed-Type Stainless Steel Turnbuckle for Curtain Wall & Railing Tensioning
The closed-type (rigid barrel) turnbuckle tensions stainless steel cables and tie rods in curtain wall, canopy and railing systems. Its enclosed barrel protects the exposed thread from dirt and tampering and gives the completed bracing line a clean, streamlined appearance that open-body turnbuckles cannot match.
Supplied with jaw/clevis or eye ends and locking nuts, the barrel turnbuckle suits vertical cable runs, diagonal canopy ties and glass railing bracing alike. Thread range covers M5–M12, with custom thread sizes available, so facade engineers can spec one body style across a project while varying the thread to suit each cable or rod diameter.
Key Features
- Material: SS304 / SS316 stainless steel for corrosion resistance
- Body type: Closed / rigid barrel turnbuckle protecting the thread
- Thread: M5–M12, with custom thread sizes available
- Design: Jaw/clevis or eye ends with locking nuts
- Finish: Mirror polished or satin brushed
- Quality: 100% inspected before shipment; material test certificates available on request
Specifications
- Thread range: M5–M12 (custom sizes on request)
- Material options: SS304 or SS316 stainless steel
- Body: Rigid closed barrel
- Ends: Jaw/clevis or eye with locking nuts
- Surface finish: Mirror polished or satin brushed
Installation & Usage
The barrel is threaded onto the end fittings at both ends of the run, then rotated to take up slack until the cable or rod reaches its design tension. The locking nuts are then run up against the barrel to hold the setting. Check that the ends are fully seated, keep gaskets and washers in place, and clean the stainless finish after final adjustment.
Quality Assurance
Every closed-body turnbuckle is 100% inspected before shipment for barrel straightness, thread engagement and surface finish. Material test certificates are available on request.
Applications
- Glass railing cable tensioning
- Curtain wall and canopy bracing
- Structural glazing and tie-rod systems
- Architectural facade bracing where a concealed thread is preferred
