Clothes dryers are responsible for over 15,000 fires a year, resulting in more than a dozen deaths and hundreds of injuries. Many are the result of inadequate venting caused by crimps and sharp bends in the flexible vent hose. The Dryerbox® reduces these problems and allows your dryer to run more efficiently by allowing the hose to contract into a metal box recessed in the wall. While designed primarily for installation in new construction, a Retro-Fit model is also available.
