Genuine tempered glass (not a translite). This particular glass is made on a heavier 4mm (thicker) panel. Beyond a replacement, perfect as a wall hanging in your gameroom, this glass is relevant all on its own. Polished corners and edges, ready for new trim and lift bar (or use your old ones). Turnkey replacement, finally get rid of that old chipped, crackled, or shedding original backglass.
