A:Answer Hello Cia,
Great question! This particular model (Ring Video Doorbell) Wedge Kit will not work with your Ring Video Doorbell 3. This is because the Ring Doorbell 3 is a bit larger than the original Ring Doorbell model. Here is a link to the proper Wedge Kit for your device: https://ring.com/products/wedge-kit-for-video-doorbell-3.
With the included screws, you are able to install one Wedge Kit piece and still use the Ring Solar Mount Charger. If you wish to use more than one wedge piece, you'll want to purchase longer screws in order to attach the additional wedge's to the Solar Charger. Here is a helpful article that elaborates on installing a Wedge Kit with your Ring Doorbell 3: https://support.ring.com/hc/en-us/articles/360039088511-Using-a-Wedge-Piece-to-Properly-Position-your-Ring-Video-Doorbell-3.
