  • Patent number: 7677506
    Abstract: An apparatus for holding a plurality of rearwardly extending coiled lines on a truck in an elevated side-by-side position for line-protection purposes includes an assembly having a first section, a second section, and components for holding the assembly together. A plurality of at least two line-gripping portions (preferably three) extend away from the elongated portion radially relative to the axis of elongation and in spaced-apart relationship to each other. The line-gripping portions define line-receiving openings with central axes extending intermediate the first and second sections generally parallel to the axis of elongation. So constructed, the apparatus provides sidewardly extending openings for receiving upwardly disposed and sidewardly extending loop portions of the rearwardly extending coiled lines.
