120mm fan to 4" hose adapter

Do you have your litter box in a basement or some other poorly vented area? Are you tired of smelling the sweet scent of doo-doo and litter? I've got a solution for you! This is a 120mm fan to 4" round hose adapter to allow you to add an extractor vent to your litter box! We use the AC Infinity AC-ATT7 for the fan routed outside through a dryer vent and not only does it nearly eliminate the scent but it also keeps the humidity down inside the litter box allowing our litter to stay fresh longer. By using a fan that isn't attached to the littler box it drastically reduces the noise, vibrations, and the worry of your curious cat sticking his paws in any fans. We use 18-gallon plastic totes for litter boxes as we have a couple of old cats that can't squat like they used to and tend to miss. I also included the file for the clip that holds the two totes together if you want to copy exactly what we have.
