Abstract: A dryer vent box and method is provided which addresses the problems inherent in conventional dryer vent assemblies. The dryer vent box includes upper and lower mating substantially rectangular housings which are dimensioned to be received within the confines of a conventional 2.times.4 studded wall. Each of the upper and lower rectangular housings have a protruding cylindrical flange with an opening into the housing to provide for the intake and exhaust of dryer exhaust gasses. The upper housing section includes at least one tab extending from one of the sides thereof to provide for the attachment of the upper housing to the wall. The lower housing includes cutoff markings or indicators which provide for the correct placement of the cylindrical flange of the upper housing relative to the dryer outlet. Thus, the dryer vent box of the present invention provides an aesthetically pleasing, effective, efficient and improved dryer venting assembly.
