Nutone 330 Inlet Mounting Plate S3865 A switch with worn internalThe Nutone 330 Inlet Mounting Plate is a central vacuum fitting that anchors a wall inlet securely to your home's pipe network. Fittings like this one are the quiet backbone of a central vacuum installation, because every loose or damaged connection is an air leak that steals suction from every inlet in the house. The plate is designed to work with standard 2 inch central vacuum pipe, and a bead of PVC cement makes the joint permanent and leak free.
