Compatible with multiple wireless doorbells: This doorbell mount accommodates various doorbell sizes using included foam pads of different thicknesses. Specifically designed for Ring Doorbell 4/3/2/1, the all-new Ring Battery Doorbell Plus (2023 model), Blink Doorbell, and Eufy Doorbell S220/C210. Note: For wireless video doorbells only, not for wired models (Doorbell not included). Which doors are suitable? It's crucial to measure your door before purchasing. This No-Drill Anti-theft Doorbell Mount is designed for doors 1.25 inches to 1.95 inches thick, with a gap of more than 0.06 inches between the door and frame. Note: Only suitable for inward-swinging doors; not compatible with outward-swinging storm doors. No-Drill Doorbell Mount: This anti-theft doorbell bracket is secured with double screws, offering more stability than standard single-screw mounts. The no-drill design prevents damage to your door panel, and the newly designed front opening doesn't interfere with the doorbell's motion detection sensor. Easy Installation & Cooling Design: Install the doorbell mount in seconds. Simply place your video doorbell in the bracket and adjust the screws to fit your door's thickness. Multiple mesh holes around the doorbell promote heat dissipation, extending the doorbell's lifespan.
