IST Intrasonic Technology­™ model R-MyDoor-B Video Doorbell & model RETRO-MDAB Adapter Plate (Set) Connects exclusively to Intrasonic Technology™ Retro-M Radio-Intercom System.Includes RETRO-MDAB Adapter Plate, which provides power to the R-MyDoor Video Doorbell Camera.RETRO-MDAB is designed specifically to attach to NuTone®, M&S Systems®, Broan® & Intrasonic Technology™ new construction recessed rough-in boxes, but will line up with the screw holes on NuTone®, M&S Systems®, Broan® & Intrasonic Technology™ Surface Mount Boxes (See photos for a better understanding.) It fits neatly on the NuTone® IA70 Surface Mount, but overhangs on the other major Surface Mount Boxes. Regardless of the type of mounting, it needs to be sealed with Silicone or other sealants. The RETRO-MDAB Adapter Plate does not come with a weather seal gasket.Just because I am showing you that this item can physically mount to a NuTone® or M&S Systems Door Speaker Rough-in or Surface Mount Box does not mean this product will connect to those intercom systems. You must already have an Intrasonic Technology™ model Retro-M Radio-Intercom System installed in place of the discontinued competitive products.The front trim panel is a separate piece on the R-MyDoor Video Doorbell Camera and can be painted easily with spray paint if you desire a custom color.Ebay 30-day satisfaction guaranty.2-Year Intrasonic Technology™ Warranty.Oh yeah, I almost forgot, FREE SHIPPING to the United States of America.If you are confused, contact me for advice....I'm not taking this back unless it is immediately defective. I would love to be able to, but there are a lot of desperados out there that like to play switcharoo. The Recessed and Surface Mount Boxes are not included—the pictures of them are there to help you understand how the IST Intrasonic Technology Adapter Plate mounts to them and what to expect in appearance.Don't like my price?—Make me an offer
