A line in contact with an elongated mandrel has incremental lengths wrapped around the mandrel when the mandrel is rotated about a longitudinal axis. The mandrel has at least one transverse handle receiving opening therethrough. The handle when inserted into the handle receiving opening is employed to rotate the mandrel. The device includes at least one member for engaging the line to prevent unwinding rotation of the mandrel. The mandrel carries spaced transverse flange plates to prevent the line from sliding off the mandrel. At least one of the flange plates has oppositely extending slots from the periphery of that one flange plate to an area near the mandrel for admitting the line from which slack is to be removed to be led into and out of the space between the flange plates to contact the mandrel.
