Quadro Clip Frame 4x10 inch Borderless Frame Borderless picture frames offer a clean gallery look and are suited to any image and decor. The frameless visual effect is ideal for art walls and collages. Quadro Clip Frame kits include specially grooved MDF backing panel, a 2mm. thick Glass Panel with Ground & Polished edges and a sufficient quanitity of clips for assembly. Simple, fast, snap together tool-free assembly is required for this frame. Silver color clips snap securely into a specially grooved channel on the MDF backing panel and are barely visible from the front. Any number of clips can be used and they can be positioned anywhere along the edge of the frame. Quadro clip frames are designed to hang directly from the clip which will be installed at the top center positon on the frame. A cutout on the back of each clip is designed to accomodate a screw or nail head. Clips slide to any positon allowing for precise levelling when hanging the frame. The total frameable thickness (image + optional matte ) is 3/16 inch. This will accommodate an image and up to a standard bevel cut double matte.
