Get quoteThe Small Clear Plastic Melon-Seed Turn Button Clip (SKU: U27) is XKY Framing’s transparency solution for backing hardware. Made from optically clear polycarbonate or ABS, this 16 mm clip virtually disappears when installed on light-coloured or transparent backing boards, preserving the clean aesthetic of contemporary frameless and acrylic displays.
In modern gallery design and minimalist home décor, hardware visibility is undesirable. The U27 Small Clear Plastic Melon-Seed Turn Button Clip addresses this by being optically transparent — when installed against a white or clear backing, the clip becomes almost invisible, letting the artwork command full visual attention.
Total length: 16 mm. Head width: 6 mm. Tail width: 6 mm. Hole diameter: 2.5 mm. Thickness: 1.5 mm. Material: clear polycarbonate/ABS.
Pre-drill 2.5 mm pilot hole. Seat backing. Align clear clip. Fasten with small 2.5 mm screw. Rotate to lock. The clip’s transparency makes it nearly invisible against white backing.

Q: What material is U27?
A: Optically clear polycarbonate or ABS for transparency and rigidity.
Q: Dual purpose with acrylic glazing?
A: Yes, on shallow shadow boxes with deep enough rabbet.
Q: Does clear plastic yellow?
A: Polycarbonate may yellow slightly over years of UV exposure; store away from sunlight.

What material is U27 made from?
U27 is made from optically clear polycarbonate or ABS, providing transparency while maintaining sufficient rigidity for small-frame backing retention.
Can U27 be used with acrylic glazing clips simultaneously?
Yes. On shallow shadow boxes, U27 can serve dual purpose: retaining both acrylic glazing on the front and backing board on the rear if the frame rabbet is deep enough.
Does clear plastic yellow over time?
Polycarbonate can yellow slightly over many years of UV exposure. For long-term clear appearance, store unused clips away from direct sunlight.
