A kit for forming a raceway assembly including a plurality of members can include a plurality of portions including channel portions and coupling portions, each of the portions extending in an axial direction and having a plurality of walls defining a generally U-shaped cross-section. Each channel portion may have at least one opening in at least one wall, and each of the coupling portions has at least one hole in at least one wall. Each coupling portion may be adapted to receive one or more of the channel portions so that axial directions of the received channel portions are aligned with the axial direction of the coupling portion and so that at least one of the openings of each received channel portion is aligned with at least one of the holes. The coupling portions and channel portions may have inter-engageable features which preclude movement of the received channel portions relative to the coupling portion other than in the axial directions thereof. In addition, the kit may include one or more non-threaded pins configured to pass through the aligned holes and openings and lock in place.
