Abstract
A fitting mounted on the bottom of a cell in a cellular raceway. A hollow cylindrical member engages and is secured to the bottom of the cell in alignment with a bore in the bottom. A junction box is mounted on the lower end of the cylindrical member and has an opening aligned with the member. Intumescent wafers are inside of the cylindrical member and are formed to permit passage of conductors. Discs restrain the intumescent wafers from expanding into the cell and junction box. Electrical conductors can extend from the junction box to the cell.
