Notifier SBB-B4 Two-Tier Backbox — CAB-4 Series
The Notifier SBB-B4 is a two-tier backbox for the CAB-4 series cabinet system. First, it accepts two chassis tiers of Notifier panel modules. In addition, the finish is black for installations where the standard CAB-B4 red is not preferred.
Notifier SBB-B4 Construction
CAB-4 series backboxes are fabricated from 16-gauge steel per the Notifier datasheet. As a result, the enclosure provides a sturdy mounting platform. Furthermore, knockouts at multiple positions ease conduit entry during installation.
Installation Notes
- Two-tier (B) configuration — accepts two chassis tiers.
- Right- or left-hand hinges are selectable in the field.
- Door opens a full 180° for service access.
- A separate trim ring supports semi-flush mounting if needed.
- Black finish.
In short, the SBB-B4 is the backbox you pair with Notifier CAB-4 doors and chassis for a two-tier black build. Therefore, confirm your door, chassis, and trim ring selections to complete the cabinet.
