Ubiquiti UACC-READER-PRO-JB-B Junction Box for Readers
Overview
The UACC-READER-PRO-JB-B is a junction box purpose-built for UniFi Professional Access Readers and UniFi Doorbells. It provides a centralized mounting and wiring consolidation point that handles the transition between field conduit runs and reader hardware. The box weighs 0.450 lb and supports both flat surface mounting and attachment to standard 3/4" electrical conduit — the most common infrastructure in commercial installations. Deploy this when you need a clean junction point that keeps cable slack managed and protects solder joints or terminal blocks from direct weather exposure.
Compatibility
This junction box integrates with the UniFi Professional Access Reader product family and UniFi Doorbell hardware. It is designed specifically for readers that expect external wiring consolidation — check your reader model documentation to confirm mounting surface requirements. The box supports standard conduit KOs (knockout holes) for 3/4" conduit, making it suitable for existing electrical infrastructure in warehouses, offices, and secure entry points where readers mount to poles, walls, or cabinet frames alongside conduit runs.
Installation Notes
Mount using either flat-surface fasteners (hardware not included — verify load rating against conduit diameter and weight of reader assembly) or by threading 3/4" conduit through the box base. Ensure the junction box is positioned to allow slack in internal wiring and does not trap moisture in low-angle conduit runs. The lightweight design means it will not support a reader if mounted upside-down without additional bracing. Plan cable entry and exit points before fastening to avoid pinching low-voltage signal wires.
