Fixed Trim Slim/Narrow Mount for the eufy Video Doorbell S4 (3K, Wired, 2026) — Solid Footing on Narrow or Uneven Door Trim
The eufy Video Doorbell S4 is a big doorbell — about 6.6 inches tall and 2 inches wide — and its factory plate wants a flat surface at least that wide. Brick-mold trim and skinny casings rarely cooperate. This low-profile Fixed Trim Slim/Narrow Mount gives the S4 a flat, 3/4-inch-wide footing that sits flush on beveled, warped or narrow trim where the eufy plate rocks or hangs off the edge.
The front of the base carries our Eufy adapter bracket, which fits the S4. Pick Eufy Video Doorbell S4 (2026) in the dropdown and that is what we print.
3D-printed on demand in the USA from weather-resistant PETG. Orders over $100 ship free. Doorbell details at eufy.com; new to the brand? Start with our Eufy doorbells guide.
