Ubiquiti UACC-Reader-JB-W Reader Junction Box provides a mounting point for UniFi Access Readers and Intercom Viewers. It is the white variant of the Reader Junction Box, intended for installations where these devices need a junction box at the mounting location.
The box supports flat-surface mounting and attachment to 3/4-inch conduit. This gives installers two supported ways to position the compatible reader or viewer, depending on the installation layout.
Use it as a mounting accessory for supported UniFi Access Readers and Intercom Viewers. The product listing identifies it as a junction box; it does not specify additional included items.
