Notifier DR-C4 — three-tier ("C" size) locking cabinet door with window for CAB-4 Series backboxes, black.
A CAB-4 cabinet is ordered as two separate halves: one DR door and one SBB backbox. The DR-C4 is the door half sized to the three-tier SBB-C4, so it is the part to order when a C-size enclosure has a bent, missing or re-keyed door, or when a three-tier build such as an NFS2-3030 still needs its closing door. The window lets the panel display be read without unlocking.
- Three tiers, "C" size — matches the SBB-C4 / SBB-C4R backbox
- Key-locked, supplied with two keys, a pin-type hinge and the hardware to mount the door to the backbox
- Right- or left-hand hinge selectable in the field; door opens 180°
- 16-gauge steel, window style, black; 20.75 lbs
Door only — no backbox, battery plate or semi-flush trim ring is included. Tier sizes do not interchange: a two-tier box needs DR-B4 and a four-tier box needs DR-D4. Order DR-C4R for red, or DR-C4B for a solid door without the window.
