Abstract: An apparatus for supporting a plurality of elongated members on a wall defining an upstanding wall surface comprises a sheet configured for mounting to the wall in substantially-planar upstanding orientation with one face disposed opposite to the wall surface, so as to be an inner face, and an opposite face of the sheet facing away from the wall, so as to be an outer face. The apparatus includes a plurality of holders each arranged to receive one of the elongated members in generally horizontal orientation and connected to the outer face of the sheet in an array forming at least one column across the sheet in which the holders are disposed in generally linear fashion one above the other between the upper and lower ends of the sheet so that the elongated members are supportable generally one above the other in horizontal orientation.
