10 black piano hinges in acrylic / polycarbonate, 24 mm long, 32 mm wide and 3.5 mm thick, with translucent double-sided tape pre-applied. A piano hinge has two equal leaves joined by a pin along its full length; it opens to 270 degrees, and the edges are polished and bevelled for a neat finish. To fit, peel off the backing and press onto a clean surface; the pressure-sensitive tape bonds on contact, so no glue or drilling is needed. The tape resists moisture, weather and temperature changes and is hard to see once fitted. Acrylic and polycarbonate are similar plastics, used interchangeably: acrylic gives good strength and UV resistance, polycarbonate higher impact and heat resistance. For small display cabinets, boxes, jewellery boxes, lids and model making. Also called continuous hinges or full-length hinges.
