Slide these clips over the edge of two or more panels to hold them together—no tools, mounting holes, or fasteners needed. Also known as U-clips, they have a U-shaped profile that pinches panels together. Barbs on each side dig into your material to keep them firmly in place. These clips are reusable, but the barbs may scratch or mark a panel when you’re installing or removing them. They’re coated with black phosphate for corrosion resistance in dry environments.
