VacPan Dustpan (Black) is easy to install in new and existing kitchen cabinets, walls or any location with very little clearance. The piping to the system can be connected from the top or the bottom. It can be installed in a normal 2 x 4 wall. Flip the door open with your toe, starting the vacuum system, and sweep the dirt into the inlet. Close the door with your toe and the vacuum will stop.
