Dundas Jafine's recessed dryer vent box allows the dryer to be pushed up against the wall of the laundry room, saving space. The box also completely protects the duct from being crushed and lint build-up is minimized due to the limited kinks and bends. The recessed dryer vent box is made of high-impact polystyrene (UL94HB rated) and has some additional features and benefits which make it unique over other dryer box products in the market. This product has a oval to round duct adapter which threads on easily to the duct and makes installation fast and easy.
