The notifier dr-d4r door assembly is a D-size door for a Notifier CAB-4 series cabinet. Specifically, it is the window-style, four-tier door in red. The door accepts four chassis. In addition, it ships with a lock, two keys, and the hardware needed for the SBB-D4R backbox.
Notifier DR-D4R door assembly fit and intended cabinet
First, the door fits a four-chassis D-size CAB-4 backbox. Then, the integrated window gives a direct view of the panel display and trouble LEDs. As a result, the cabinet reads at-a-glance without unlocking.
In addition, the installer hinges the door on the right or left side in the field. Therefore, the cabinet adapts to either side of the mounting wall. Furthermore, the door opens a full 180° for clear service access.
