Pull Out Trash Base cabinets with Servo Drive feature a full length door front and one 10″h drawer box. The 15″w and 18″w cabinets contain one 50qt waste bin, whereas the 21″w cabinets contain two 35qt waste bins. The trash unit automatically opens with a simple touch to the door front using a hand or knee. Slightly push it in and the trash unit will softly and effortlessly close on its own. The Servo Drive allows for handless operation which aids in keeping the cabinet clean and reduces the spread of bacteria. Pull Out Trash Base cabinets come in set sizes to accommodate waste bins and are not customizeable when it comes to width. The Servo Drive feature requires electricity, so it is recommended to place this cabinet near a sink or other appliance.
