U04-Extra Large Metal Turn Button Clip (Black)

Extra Large Metal Turn Button Clip Black – U04 Complete Guide

The Extra Large Metal Turn Button Clip Black (SKU: U04) is the flagship of XKY Framing’s melon-seed clip series. With a 30 mm total length and a 3.2 mm mounting hole, it is purpose-designed for oversized picture frames and canvas stretcher bar assemblies.

Large-format artwork demands fasteners that match the scale and weight of the piece. The U04 Extra Large Metal Turn Button Clip Black uses 0.8 mm thick cold-rolled steel across its full 30 mm length, distributing clamping force over a wider area and reducing the risk of backing board deformation under load.

Total length: 30 mm. Head width: 8 mm. Tail width: 9 mm. Hole diameter: 3.2 mm. Thickness: 0.8 mm.

Pre-drill a 3.2 mm pilot hole in the frame moulding. Seat the backing board. Position the Extra Large Metal Turn Button Clip Black and fasten with an M3.5 screw. Rotate 90° to lock. Recommended clip spacing: every 120 mm for frames over 100 cm span.
