Get quoteThe Plastic Wire Turn Button Clip Black (SKU: U31) is the dark-finish, extended wire-guide version of the U30 yellow clip. Its matte black ABS construction and 20 mm wire guide tail make it the professional’s choice for frames where picture wire routing must be both functional and visually discreet.
In gallery and hospitality settings where frame backs may be occasionally visible, matte black hardware is the standard of refinement. The U31 Plastic Wire Turn Button Clip Black provides all the wire-routing advantages of the U30 while blending seamlessly with dark frame mouldings and professional back-of-frame finishing.
Clip body: 18 mm. Wire guide extension: 20 mm. Head width: 7 mm. Tail: tapered. Wire channel: 2 mm. Body thickness: 1.5 mm. Material: black ABS.
Thread hanging wire through the 20 mm longitudinal guide slot. Position clip over pilot hole. Fasten with 2 mm screw. Rotate to lock backing and guide wire simultaneously. The slot prevents wire from twisting or crossing other clips.

What is the difference between U30 and U31?
U30 is yellow with an 18 mm clip body. U31 is black with an extended 20 mm wire guide portion, providing more wire routing length for larger frames.
How does the wire guide on U31 function?
The 20 mm extended tail includes a longitudinal slot that captures and guides picture wire along the clip's axis, preventing wire twisting against the backing board.
Is U31 suitable for heavy artwork?
The clip itself is plastic and should support frames up to 5 kg when 6+ clips are used. The wire capacity depends on the wire specification, not the clip material.
