AbstractA corner piece is adapted to be installed over a corner of a metal casket having a predetermined number of tack welds securing adjacent side and end panels to one another. The corner piece extends from the top to the bottom of the casket and includes outwardly projecting top rail and bottom rail parts together with an intermediate recessed part which mate with the casket top rail, bottom rail and intermediate section, respectively, at each corner. A downwardly projecting lip at the top of the corner piece engages with internal surfaces of the top rail and upwardly projecting surfaces at the bottom are received by recess surfaces of the bottom rail in securing the corner piece to the casket. Each corner piece is sufficiently resilient to permit the ends to be flexed and spread apart thereby facilitating mounting of the corner piece. Supplemental securing means in the nature of an adhesive as well as sealing compound are adapted to be interposed between interior surfaces of the corner piece and exterior surfaces of the casket corner. Recesses are also provided in the corner piece to receive any projecting or protruding parts of the tack welds which secure the side and end panels to one another.
