Abstract: A multi-channel duct for enclosing conductors, cables, wires, power lines, communications lines and the like. The multi-channel duct includes an elongated base with an elongated divider dividing the base into two channels, and a pair of elongated covers with the outer cover overlying both channels and the inner cover overlying one of the channels. Preferably, the inner cover is integrally formed with the divider and has a precurved portion for preloading the inner cover when in its closed position. The divider and inner cover are preferably detachable from the base by a frangible seam for converting the two channel duct to a single channel duct.

Abstract: A device box having a cover member and a base member releasably coupled together by a snap-fit latching arrangement. Preferably, both the cover member and the base member are integrally molded as one-piece, unitary members with only non-hidden surfaces so that they can be manufactured by straight draw-type injection molding techniques, rather than by molds using sliders. The latching arrangement of the preferred embodiments includes one or more latch members resiliently coupled to the base member for releasably engaging one or more apertures in the cover member.

Abstract: A partition for dividing an electrical or telecommunications device box having a substantially planar dividing member with at least one retaining member extending therefrom for cooperating with a mounting post on the base member of the box to support the dividing member substantially perpendicularly to the base member. The partition is removably retained in the box by the retaining member frictionally engaging the post. The retaining member has a specific amount of interference to cause the spring action in the material and to create gripping forces around the mounting post.
