Sleeve Coupler

Sleeve Couplers are scaffolding fittings used to connect two tubes end-to-end, ensuring straight alignment and structural strength in scaffold assemblies. They comply with ASTM, DIN, and EN standards and are manufactured in forged or pressed steel for durability and safety. Hot-dip galvanized or stainless steel finishes provide long-lasting corrosion resistance for outdoor construction environments. Their design provides high axial load capacity, making them suitable for vertical and horizontal tube connections. They are widely used in building construction, industrial scaffolding, and heavy-duty projects requiring extended tube lengths.
