Large Metal Turn Button Clip Black – U03 Complete Guide
The Large Metal Turn Button Clip Black (SKU: U03) is the heavy-duty solution for securing backing boards in large picture frames. Stamped from 0.8 mm cold-rolled steel, this clip withstands the stresses placed on large-format frames during transport, hanging, and environmental changes.
When a frame exceeds 50 cm in either dimension, the forces on backing clips increase substantially. The U03 Large Metal Turn Button Clip Black uses thicker 0.8 mm steel compared to the U02’s 0.4 mm body, effectively doubling the shear resistance per clip. The 23.5 mm total length also provides a wider locking contact area against the backing board edge.
Total length: 23.5 mm. Head width: 8 mm. Tail width: 8 mm. Hole diameter: 3 mm. Thickness: 0.8 mm.
Insert backing board. Position the Large Metal Turn Button Clip Black over the rabbet edge. Fasten through the 3 mm hole. Rotate to lock. For professional installations, use a torque screwdriver set to 0.4 N·m to avoid over-tightening the thin moulding.
Best suited to frames 50 × 70 cm and larger. For medium frames, see U02 Medium Metal Turn Button Clip . For the largest frames, see U04 Extra-Large Turn Button Clip .
0.8 mm cold-rolled steel, matte black electrophoretic coating, RoHS-compliant.
Application Scenarios
U03-Large Metal Turn Button Clip (Black) serves gallery, retail, and e-commerce frame assembly where reliable hanging hardware, connectors, and finishing accessories determine customer satisfaction. Installers and production teams specify quantities per frame size and mounting environment (wall, easel, security fixings).
Wholesale buyers and contract framers source these parts for bulk trade packs — consistent plating, thread standards, and carton counts reduce picking errors on fast-moving SKUs. The product suits both workshop stock and export cartons bundled with finished frames.
