A pin structure for a wiring duct and wire holder modular system for use in wiring electrical equipment as used in control panels and electrical cabinets for machine tools, industrial installations, computers and the like, consisting of modular units for supporting and distributing to electrical equipment a plurality of electrical conductors which are routed through a plurality of wiring duct modular units interlocked end to end or at a right angle to each other for forming branching wireways, or T-connections, and turns, or L-connections. Each modular unit consists of a base member and of a row of pins mounted on two parallel edges of the base member, each pin having a tapered foot portion for insertion into a mounting aperture in the base member comprising laterally projecting flange sections of a major dimension slightly larger than the diameter of the mounting aperture in the base member, a peripheral groove being disposed proximate the projecting flange sections and being so dimensioned as to snugly fit in the mounting aperture. The pins are provided with an enlarged head portion so as to form between consecutive pins a space through which individual electrical conductors may be routed through the sidewall of the guideway.
