PoE+ Adapter Housing Spacer for Ring Wired Doorbell 4K Pro (3rd Gen) - Optional Wall Plate

Overview Designed for professional Ring integrators, low-voltage installers, and structured-cabling contractors, this PoE+ Adapter Housing Spacer by Hidden River Lab provides a purpose-built mounting cavity behind the Ring Wired Doorbell 4K Pro PoE (3rd Gen), Model 5DFYA2. The device was previously marketed as the Wired Doorbell Pro PoE (3rd Gen). The spacer addresses a common integration challenge: locating the separate Ring OEM PoE+ power/network adapter and organizing its Ethernet and USB-C connections when there is no practical recessed space at the cable exit. The housing provides a designated internal compartment for the module and a controlled route for cable slack, without presenting the assembly as a general-purpose electrical junction box. The spacer is approximately 1.5 inches deep and incorporates an internal ribbed geometry designed with passive heat distribution and component spacing in mind. These features do not constitute a tested thermal rating or make the enclosure a certified heat sink. Choose Spacer Only for a compact installation at a suitable wall location, or Spacer + Wall Plate for additional cable-management room, coverage of previous mounting marks, and installation over a suitable standard single-gang electrical box. Both choices use the same core spacer. Compatibility ✔︎ Designed for: ▪︎ Ring Wired Doorbell 4K Pro PoE (3rd Gen) — Model 5DFYA2; also known as Ring Wired Doorbell Pro PoE (3rd Gen). ✔︎ Installation type: Professional PoE+ doorbell deployments using the compatible OEM Ring PoE+ adapter and USB-C connection. ✔︎ Mounting purpose: Spacer enclosure for the OEM module and cable slack behind the original Ring doorbell mounting plate. ✔︎ Wall plate option: Optional matched plate for supported flat-wall locations and standard single-gang electrical boxes. ✔︎ Camera angle: Straight mounting; no intentionally added horizontal side angle or vertical incline. ✔︎ Mounting surface: Suitable flat, structurally sound surfaces. ✖︎ Not compatible with / not intended for: ✖︎ Ring Wired Doorbell 2K Plus (2nd Gen) — Model 5DFYA3, and Wired Doorbell 2K (2nd Gen) — Model 5DFYA4. ✖︎ Previous Ring Wired Pro generations, Ring Elite models, and other Ring doorbells not specifically verified for this housing. ✖︎ Ring Battery Doorbell models or video doorbells from other manufacturers. ✖︎ Non-flat or profiled siding surfaces without a separately validated installation method. ✖︎ Use as a generic PoE+ injector, Ethernet switch, electrical junction box, waterproof electronics enclosure, or replacement for any required OEM power component. Important — professional installation: Verify the exact Ring device, OEM PoE+ module, cable routing, connector clearance, mechanical support, and service access before installation. The standard hardwired 4K Pro shares the doorbell housing geometry, but this product is specifically intended to solve the PoE+ adapter placement problem. Important — OEM PoE+ Adapter Restriction: Ring specifies that its PoE+ Adapter is intended for indoor use only and must not be installed where exposure to water or moisture is possible. The Hidden River Lab mounting spacer does not change or supersede Ring's installation requirements. Enclosing the OEM adapter inside the spacer does not constitute approval for outdoor operation. See Ring's official installation instructions. Mounting Kit Options Choose one Mounting Kit option at purchase: ▪︎ Spacer Only — HRF00-RWPRO-P: One dedicated PoE+ module housing spacer, approximately 1.5" deep. Appropriate where the mounting surface is sound and the available cable slack can be accommodated inside the spacer cavity. ▪︎ Spacer + Wall Plate — HRP00-RWPRO-P: The same spacer plus its purpose-built matching wall plate. Adds a larger rear mounting interface and additional space for Cat5e/Cat6 cable management. The wall plate can help conceal previous screw holes, paint marks, and other cosmetic defects or be used over a suitable standard single-gang electrical box. The wall plate is not a standalone product. It is manufactured for this HRL spacer and is offered only as part of the spacer-and-plate kit. Each selected Mounting Kit contains one spacer, not two interchangeable spacer bodies. Color: Select an available production color as a separate Shopify variant. The chosen kit determines the supplied components; color does not change the housing design or doorbell compatibility.
