Long Dotted Metal Turn Button Clip Silver – U11 Complete Guide
The Long Dotted Metal Turn Button Clip Silver (SKU: U11) is an anti-vibration evolution of the long clip design. A precision-raised dot on the clip body creates mechanical interference against the backing board surface, keeping the clip locked even in environments subject to vibration, such as transport vehicles or busy galleries.
Why Choose the Long Dotted Metal Turn Button Clip Silver?
Ordinary turn button clips can gradually rotate back to the open position when frames are moved or when vibration is present. The U11 Long Dotted Metal Turn Button Clip Silver solves this with a raised dot that physically prevents counter-rotation, ensuring your artwork stays securely enclosed during transit and display.
