Abstract: An electrically conductive article support rack is disclosed. The article support rack may include an electrically conductive support beam, an electrically conductive cross-bar having at least one support to support an article in electrical connection with the cross-bar, and an attachment device electrically connecting the support beam to the cross-bar, the attachment device including: a receptacle having an inner surface, wherein the receptacle is electrically conductively attached to one of the support beam and the cross-bar, and a clip electrically conductively attached to the other of the support beam and the cross-bar, the clip moveably engaging the inner surface to abrade at least a portion of the inner surface of the receptacle to remove non-conductive material from at least a portion of the inner surface of the receptacle.

Abstract: An electrically conductive attachment system is disclosed. The attachment system may have a tubular portion of electrically conductive material adapted to be attached to a support beam, and a mounting clip adapted to be attached to a cross-bar and to releaseably engage the tubular portion. The mounting clip may have an attachment portion adapted to be attached to a cross-bar and to releaseably engage the tubular portion having an attachment portion adapted to electrically connect the mounting clip to the cross-bar, and an engagement portion adapted to be inserted through a top opening of the tubular portion engaging an inner surface of the tubular portion and providing an electrical connection between the tubular portion and the mounting clip. The attachment system may be capable of releaseably connecting the cross-bar substantially transverse the support beam and providing an electrical connection therebetween.
