The Edwards 3-CAB14B is an EST3 lobby-enclosure wallbox with two chassis spaces (14 module positions total). First, the wallbox mounts semi-flush in a wall opening or surface-mounts to a finished wall. Then, the EST3 chassis, power supply, and modules drop into the wallbox. As a result, the 3-CAB14B is the structural foundation for a medium-size EST3 panel installation.
Specifically, the “B” suffix designates the wallbox-only (no door, no chassis included). Therefore, order the matching door (3-CAB14D for gray, 3-CAB14DR for red) and the appropriate chassis modules separately. In addition, the contoured profile matches the rest of the EST3 cabinet family.
Edwards 3-CAB14B construction
The wallbox is fabricated from #14 AWG cold-rolled steel with a gray baked-enamel finish. Furthermore, both surface and semi-flush mounting are supported from the same part. Also, knockout provisions accommodate the typical conduit landings for an EST3 lobby panel.
Verified specifications

- Finish: gray baked enamel
- Capacity: two chassis spaces (14 local rail module positions total)
- Mounting: semi-flush or surface
- Surface dimensions: approx. 35.5″H x 24.0″W x 3.86″D
- Semi-flush finished opening: approx. 37.75″H x 27.34″W x 5.5″D
- Door (sold separately): 3-CAB14D (gray) or 3-CAB14DR (red)
- Reference datasheet: E85010-0067 EST3 Cabinets and Chassis
The 3-CAB14B is a passive enclosure, so it carries no standalone UL listing. However, the assembled EST3 panel — wallbox, chassis, power supply, modules, and door — is covered by the system listing under UL 864. As a result, the 3-CAB14B contributes to a fully-listed installation when paired with the OEM-specified modules and door.
