Authentic part manufactured by eufy. Used for adjusting the installation angle and direction. Compatible with eufy Security S330 Video Doorbell(Wired) (E8203)
We have a slightly recessed entryway, so this 15-degree tilt was exactly what we needed to point the camera down the walk instead of at the neighbor's fence. The fit is snug against the doorbell and hasn't budged in a week of storms.
The wedge is solid and clicks into place with the doorbell mount exactly as it should, fixing my side-angle view of the walkway. It's a genuine eufy part, so there's zero guesswork on compatibility—my doorbell now faces straight out instead of at the porch pillar.
Installation took under five minutes and the wedge locked right into place. My doorbell now points down the porch instead of across the street, and the angle adjustment is exactly what the listing described.
