Large Silver Arch Turn Button Clip – U12 Complete Guide
The Large Silver Arch Turn Button Clip (SKU: U12) introduces a spring-action arch design to the turn button clip family. The 3 mm bow pressed into the clip body creates inherent spring tension that locks the backing board firmly in place without requiring precise screw torque, making it an excellent choice for framers who want quick, reliable backing installation.
Why Choose the Large Silver Arch Turn Button Clip?
Traditional flat clips require careful torque control — over-tighten and the moulding cracks; under-tighten and the backing rattles. The U12 Large Silver Arch Turn Button Clip self-regulates clamping force through its 3 mm arch, delivering consistent results every time.

FAQ
Q: What is the benefit of the 3 mm arch?
A: It creates spring tension when locked, pressing the backing board firmly without over-tightening.
Q: Does the arch affect clip height?
A: Yes, it protrudes 3 mm above the frame plane. Account for this with hanging hardware.
Q: Is 0.3 mm steel durable enough?
A: Yes. The arch geometry distributes stress and provides a tactile click when locked.
