Large Black Arch Turn Button Clip – U13 Complete Guide
The Large Black Arch Turn Button Clip (SKU: U13) brings the spring-action arch mechanism of the U12 to frames that demand a dark finish. Its 6 mm narrow tail and 3 mm arch deliver precise, tool-free backing retention for dark-stained, black, or ebony picture frames.
Why Choose the Large Black Arch Turn Button Clip?
The 3 mm arch in the U13 Large Black Arch Turn Button Clip creates spring clamping force automatically upon rotation. This eliminates the need for precise torque control, reduces installation time, and ensures a consistent, rattle-free backing for every frame.
