Japanese Type Scaffolding Beam Clamp / Girder Coupler / Gravlock Coupler
Scaffold Beam Clamp, also known as Girder Coupler, is specifically designed for connecting scaffolding pipes to steel beams or other structural sections. It provides secure and stable connections between scaffolding and beams. These should always be used in pairs for maximum safety.
Main Advantages:
• High Skid Resistance: Large contact area between tube and coupler.
• Crack Resistance: Drop forged steel provides high strength.
• Corrosion Resistance: Electro-galvanized finish prevents rust.
• Robust Fastening: Equipped with high-strength T-bolts.
