Abstract: Hardware for mounting a rail to a vertical wall includes two sets of hardware, each set including a wall piece and a rail piece. Each wall piece includes a wall mounting plate screwed to the wall, a threaded shank extending integrally outwardly from the wall mounting plate on a shank axis, a cylindrical disk-like rail piece mounting head integral with the outer end of the shank and inscribed on its face with radially extending scribe lines, and a rail piece clamping nut threadably mounted on the shank between the wall mounting plate and the mounting head. Each rail piece includes a rail mounting plate screwed to the rail and a rail piece mounting head receiving plate offset outwardly from the rail mounting plate. This mounting head receiving plate is provided with a shank receiving slot and is inscribed with a scribe line on the axis of this receiving slot.
