Qubelok is a light fabrication system of square hollow aluminium tubes and accessories, including connectors, castors and end caps. Lipped tubing allows you to insert timber, particle board, glass or perspex for shelving or surface tops. Anyone can put together the Qubelok system. You can make just about anything that requires square joining and framing. All you need is the square aluminium tubing, connectors and your toolkit of a hacksaw, a file for smoothing rough edges and a tube of adhesive.
