Abstract: The present invention constitutes an electrical mounting and conduction means having a support element having a generally U-shaped interior surface, the base of the exterior of the support element being in thermal contact with a heat dissipating surface; a carrier element having a generally U-shaped exteriorsurface, the surface having a cross-section of smaller dimension than that of the U-shaped surface of the support element, the carrier element being nestable within the support element; and locking means removably securable to adjacent arm members of each of the support and carrier elements for maintaining the support and carrier elements in selective securement to each other.
