Abstract
Abstract A fixture suitable for convenient and rapid attachment to structural surfaces, especially masonry-type surfaces, which has a thermoplastic resin mounting portion which can be softened and pressed against the structural surface and bonded thereto without further means of attachment. The fixture may have a fuel adhered to the mounting portion which upon ignition by a flame will burn to soften the thermoplastic resin to a bonding state.
