Mates easily with CMI's Maxi Rigplate (sold separately) to offer eight rigging points for running high lines, removing large chunks of wood over precarious positions, or other rescue scenarios. (For rope only. Not for use with steel cable. When mated to the Maxi Rigplate, the systems MBS is 13,000 pounds.) "
