ABSTRACT:
A new, safe and sanitary edge trim for use with commercial ventilation hoods usually located over stoves and ovens is disclosed. The edge trim is particularly suitable for use with ventilation hoods over cooking units where the fumes to be exhausted may carry large amounts of grease and/or fats. The trim of this invention includes a slit cylindrical stainless steel member which tightly fits over the edge of a side wall of the ventilator to which the trim is to be added. The cylindrical member is spot welded to the stainless steel ventilator sidewall with a stainless steel welding rod and a heli-arc welder at spaced locations along the joint. A bead of suitable grease or animal fat imperveous putty or other filler material is located on both surfaces of the ventilator side along the full length of the juncture of the ventilator side and the slit stainless steel cylindrical member. Thus, there is achieved an edge trim which is not hazardous if struck by ones head, and which at the same time prevents the accumulation of grease and animal fat. The edge trim of the prior art ventilator hoods presented both a fire hazard and a location for the growth of germs and bacteria.
