Round Disc Metal Turn Button Clip Black – U22 Complete Guide
The Round Disc Metal Turn Button Clip Black (SKU: U22) reimagines the turn button clip as a 12 mm diameter steel disc with an off-centre 3 mm hole. Unlike elongated clips that lock only at 90°, the U22’s circular body can lock at any rotational position, providing unmatched flexibility for unusual frame shapes and tight installation spaces.
Standard clips require precise angular alignment to achieve their locked position. The U22 Round Disc Metal Turn Button Clip Black eliminates this constraint — its circular profile means that once pivoted to any angle where the disc edge overhangs the backing board, it provides a secure lock. This is invaluable for round frames, polygon frames, and any backing board where the rabbet direction is irregular.
Diameter: 12 mm. Hole diameter: 3 mm (off-centre). Thickness: 0.4 mm. Shape: round disc.
Position the disc with hole aligned to pilot hole. Fasten with M3 screw, finger-tight. Rotate disc so its edge overhangs the backing board. Tighten screw fully to lock. The disc can be set at any angle.

Application Scenarios
U22-Round Disc 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.

FAQ
How does a disc clip lock?
The off-centre 3 mm hole is the pivot. When rotated, the edge of the disc overhangs the backing board, creating the locking contact. It can lock at any angle, not just 90°.
What frames benefit most from disc clips?
Round, irregular-shaped, and small square frames benefit most from the U22's 360° locking flexibility.
How many U22 clips per frame?
For small frames up to 20 × 20 cm, 4 clips are sufficient. For irregular shapes, use 1 clip every 80 mm along the backing perimeter.
Can this machine be customized?
Yes. U22 supports OEM customization including voltage (110V/220V/380V), pneumatic requirements, tooling, and export packaging. Share your moulding profile, daily output target, and destination market — our engineering team will confirm a factory-direct specification and lead time.
Do you provide overseas technical support?
Yes. XKY Framing provides remote commissioning guidance, spare parts supply, and video troubleshooting for hardware installations worldwide. For larger framing lines we can arrange on-site support by appointment. Contact us with your order reference for dedicated after-sales assistance.
