Abstract
The folder is formed from a single sheet, folded along a fold line to form opposing walls. Each wall, at its top, includes a retaining portion that folds over a metal or plastic channel rod and includes a series of horizontally-spaced holes. The holes extend vertically over the lower edge or a rib of the channel rod. Each channel rod extends laterally past the edge of the folder and includes notches or hook ends that engage a pair of rails. Each tab includes a clip portion that opens downward. The clip portion includes two vertically-oriented inner faces, one or both of which includes inward-facing dimples or protrusions that fit at least partially into the holes in the retaining portion. At least one optional protrusion may be locating, meaning that the top of the protrusion does not engage the channel rod when the tab is fully attached.
