BOTH SIZES, SO YOU DO NOT HAVE TO GUESS - one tall and narrow mount, 5.9 x 2 in, and one shorter and wider, 5 x 2.45 in. Measure nothing, order once, use the one that suits your doorbell. Not compatible with the Elite.
IT DOES MORE THAN A STICKY PAD - plenty of video doorbells come with screws and wall plugs but no adhesive at all, so there is no no-drill option in the box. This mount also acts as a spacer, and it has cut-out tabs: open one with a craft knife and you can bring a power cable in from above or below, so a wired doorbell can go up without drilling through the door.
WHAT YOU ACTUALLY DO - wipe the back of the mount and the spot on the door, stick the round pads onto the mount first, then press the mount firmly into place and leave it to set. The plate that came in your doorbell box then fixes onto the mount with the stainless steel screws we include. That plate belongs to your doorbell and is not supplied with this mount. No drill, no wall plugs, nothing goes into your door.
YOUR MOTION ALERTS KEEP WORKING - the mount sits behind the doorbell and clear of the sensor window, so it does not block motion detection. And because nothing is drilled, there are no screw holes left in your door or door frame.
SMOOTH, SOLID SURFACES ONLY - AND IT ADDS 0.59 IN OF DEPTH - it grips smooth vinyl, glass, glazed tile and painted metal. It will not hold on brick, stone, stucco, rough render or flaking paint. The adhesive is deliberately strong, so on a painted surface it can lift the paint when it comes off - worth knowing before you choose the spot. The mount is 0.59 in (15 mm) thick, which is what makes room for a cable to pass behind it, so your doorbell will sit that much further out from the door.
