Abstract: An assembly for supplying power to a system of modular wall panels may include a housing, a lid, and a sleeve positionable on a conduit and disposed between the lid and housing. The sleeve is configured to have a predetermined shape that cooperates with structure on either the lid, the housing, or both to fix the conduit in a plurality of different orientations or positions with respect to the housing and lid. The sleeve may include positioning means, such as a key, and the housing may be configured to include an opening in which the positioning means is selectively positionable in a first orientation whereby the conduit assumes a first position with respect to the housing and a second orientation whereby the conduit assumes a second position with respect to the housing that is different than the first position. The housing may include a second opening in which the positioning means is disposed when the conduit assumes the second position.
