What is a Forged Swivel Coupler?
A forged swivel coupler is a scaffolding tube connector designed to join two scaffold tubes at any required angle. Unlike fixed couplers that create rigid 90-degree joints, a swivel scaffold coupler rotates freely, making it ideal for diagonal bracing, cross bracing, curved structures, and non-standard scaffold layouts.
Common industry names include:
- Swivel scaffolding clamp
- Double swivel coupler
- Drop forged swivel clamp
- All-angle coupler
- Universal scaffolding clamp
- Rotating pipe clamp
- Diagonal brace coupler
- Rotation scaffolding clamp
These couplers are essential for creating safe and stable scaffolding structures in demanding construction environments.

48.3 × 48.3 mm Swivel Scaffolding Clamp
The 48.3 × 48.3 mm Forged Swivel Coupler serves as the international standard for tube-and-coupler scaffolding systems. Contractors rely on this swivel scaffolding clamp for diagonal bracing, cross bracing, access scaffolds, façade scaffolding, and general construction projects.
48.3 × 60.3 mm Double Swivel Coupler
The 48.3 × 60.3 mm Double Swivel Coupler securely connects standard scaffold tubes with heavy-duty tubes in mixed scaffold systems. Engineers specify this all-angle coupler for industrial plants, infrastructure projects, formwork systems, and temporary support structures that demand flexibility and strength.
50 × 50 mm Forged Swivel Coupler
The 50×50 mm Forged Swivel Coupler creates a secure rotating connection between two 50 mm scaffold tubes. Contractors install this coupler in industrial scaffolding, staging systems, structural steel projects, and maintenance platforms that require reliable tube connections.
60.3 × 60.3 mm Heavy Duty Swivel Coupler
The 60.3 × 60.3 mm Heavy Duty Forged Swivel Coupler supports bridge construction, heavy-duty scaffolding, shoring systems, industrial maintenance, and infrastructure projects. Its high-strength drop forged steel construction delivers superior load capacity, durability, and long-term performance under demanding site conditions.
International Swivel Coupler Size Chart
AMCO Exports supplies EN74 swivel couplers and BS1139 swivel scaffolding clamps for global scaffolding standards and regional construction requirements. Our scaffolding tube connectors are available in standard, reducing, and heavy-duty sizes compatible with international tube dimensions used across Europe, the Middle East, Asia-Pacific, and Africa.
| Tube Size Standard | Compatible Tube O.D. | Typical Application | International Standard |
