Medium Metal Turn Button Clip Black – U02 Complete Guide
The Medium Metal Turn Button Clip Black (SKU: U02) is a versatile, precision-stamped steel fastener designed for mid-size picture frames. With its 20 mm length and 0.4 mm thin-steel profile, it delivers reliable backing-board retention with minimal visual impact.
Why Choose the Medium Metal Turn Button Clip Black?
The U02 Medium Metal Turn Button Clip Black bridges the gap between the compact U01 and the heavy-duty U03. Its 0.4 mm body flexes slightly during installation, self-centering against the backing board edge for a gap-free fit. This flexibility also means the clip accommodates minor variations in rabbet depth without bending permanently.

FAQ – Medium Metal Turn Button Clip Black
Q: How does the U02 differ from the U01?
A: The U02 is longer (20 mm vs 16.5 mm) and thinner (0.4 mm vs 0.8 mm), making it more flexible and suited to mid-size frames with thinner rabbets.
Q: What is the maximum frame weight for U02?
A: Recommended for frames up to approximately 5 kg when four or more clips are used evenly spaced.
Q: Does the thin 0.4 mm body reduce durability?
A: Not for standard indoor use. The cold-rolled steel at 0.4 mm provides sufficient spring tension to hold backing boards securely.
