摘要: A roofing safety device, adapted to be used in connection with substantially all roof configurations comprises an upright support, secured the of a building, having at least one self-braking mechanism and cable assembly attached thereto. Disposed free end is fastening device which may plurality heavy rings belt. The provided on belt enables worker attach either side his body, thereby allowing perform task without being chafed by cable. pair stabilizing struts, each rectangular foot distal ends thereof are rotatable about orthogonal axes conform any rooftop configuration. ability virtually rooftops, combined non-irritating manner increases likelihood that will habitually, so as reduce number injuries deaths.
