Abstract: An improved attaching clip is disclosed for use with a roll of steel wire mesh reinforcing that is designed to be utilized in concrete negative buoyancy coatings. The clip is secured to the leading or free end of the roll and may be used to connect the leading end of the roll to the remaining portion of the roll so as to prevent the unrolling of the roll during storage and handling. The clip may also be utilized to connect the leading end of the roll to the trailing end of another similar roll of steel wire mesh reinforcing so that the two rolls form a continuous strip of steel wire mesh reinforcing so as to facilitate the installation of the reinforcing.
