Abstract: An end block adapted for use on a kiln car and for retaining a resilient refractory member which bridges between the kiln car and an adjacent kiln car includes a refractory body having a transverse recess. The recess includes an enlarged cavity and a neck portion connecting the enlarged cavity to the end face of the end block adjacent the end of the kiln car. The resilient refractory material bridges between the end blocks on adjacent kiln cars. One end of the resilient refractory material is retained by the recess in one end block and the other end extends into the recess in the end block on the adjacent car or contacts the end face of the end block on the adjacent car. The recess may be off center so that two layers of resilient refractory material may bridge between the two adjacent kiln cars.
