Notifier SBB-B4 — CAB-4 Series backbox assembly, two tiers, black.
Notifier ships CAB-4 cabinets as separate pieces so the enclosure can be roughed in and conduit pulled before the panel electronics arrive. Tier count sets the usable chassis and dress panel space, and it is where ordering goes wrong: the SBB-B4 is the two-tier B size, while the similar-looking SBB-A4 is the one-tier A size. A door sized for one will not fit the other.
- Two tiers, B size; SBB-A4 is one tier, SBB-C4 three tiers, SBB-D4 four tiers
- 16-gauge steel, black — SBB-B4R is the red equivalent
- Weight 26.88 lb
- Field-selectable right- or left-hand hinge; door opens 180°
- Matching doors: DR-B4 window, DR-B4B solid, ADDR-B4 for a top-row CA-2 chassis
- Optional TR-B4 semi-flush trim ring, opening 24.062" W × 28.562" H
- CAB-4 Series UL/ULC listed, S635
Backbox only. The door, the BP2-4 battery plate and the trim ring are each ordered separately, and seismic-certified jobs also need the SEISKIT-CAB kit.
