摘要： Magnetic holder for keys and the like embodying this invention is in the form of a unitary extrusion of synthetic plastic, magnetic material. The extrusion has a planar web portion, and a key-shaped cut-out is provided through the base portion of said magnetic material. The extrusion includes longitudinal, inwardly opening side edge channels, and the sheet is slidably insertable within said channels as a closure for one side of said key shaped cut-out.Also disclosed is a method of manufacturing such key holders which includes the steps of extruding a unitary, continuous strip of synthetic plastic magnetic material with a planar web portion and inturned longitudinal edge channels. A key-shaped cut-out is punched through the web portion of the magnetic strip, and a flat panel is fitted over one side of the key-shaped cut-out, with the edges of the panel disposed in said channels.
