ABSTRACT:
A wiring duct, or wireway, of the type used in electrical equipment for supporting and retaining electrical conductors and for permitting individual conductors to be routed to and from the wiring duct, in the form of a U-shaped channel having sidewalls, at least one of which has a plurality of longitudinally spaced slits open to the edge of the wall defining a plurality of flexible finger-like members. Each slit is substantially wider at one end than the other and has sides diverging at a predetermined angle towards the edge of the sidewall but terminating proximate each edge by a narrow gap restriction permitting passage of the conductors routed through the slit as a result of the deflection of the flexible finger-like members. The width of each slit at its widest portion is at least 1.5 that of its width at its narrowest portion.
