ABSTRACT:
A catalytic converter device, useful with a self-cleaning oven, is provided. The device includes (a) a dish-shaped body formed of a mesh of metal strands, the body having a base member, sidewalls projecting from the base member, and a flange extending out from the sidewalls, the mesh having a plurality of apertures therethrough; (b) a catalytic material on at least the surface of the mesh; and (c) one or more locking tabs extending from the sidewalls, wherein the locking tabs and flange cooperate to secure the device within an orifice of a gas vent so exhaust gases will pass through the apertures. The locking tabs can be formed by punching a hole in the sidewall, such that each locking tab remains integral with the sidewall, the locking tab projecting from an edge of the hole distal the flange and at angle toward the flange.
