This is a new glass is 3/16 thick and about 15 3/8 X 8 7/8 in the center and 7 5/8 on the rt and left ends with an arch top. This glass fits the Endeavor and earlier stoves by Lopi. this door is the one with a large heavy inside trim ring.  We buy large sheets of ceramic stove glass by the case direct from the ceramic glass distributer. We cut them to size and wet sand the edges for a safe custom fit. This is the same high temp glass used by Lopi for a fraction of the cost. Thanks for looking
