Wall-Mount Fiber Enclosure
The Black Box JPM402A-R3 is a locking wall-mount fiber enclosure designed for indoor network installations. It provides secure, organized termination for fiber optic cables in equipment rooms, wiring closets, or office environments. The unit suits network administrators and installers who need a compact, lockable cabinet to protect patching and splicing hardware from unauthorized access.
Four-Slot Capacity and Low-Profile Depth
The enclosure offers four slots for adapter panels or splice trays, giving enough headroom for small-to-medium fiber counts in a single cabinet. Its 3.3-inch depth keeps the profile tight against the wall, conserving space in crowded corridors or shallow recesses. Installations requiring higher port density or deeper splice management will exceed the available slot count and internal volume.
Replaces Open Racks and Unsecured Boxes
This cabinet upgrades from open wall brackets or non-locking plastic boxes where physical security and dust protection are lacking. The jump is worth it when the site demands a metal cold-rolled steel chassis with a locking front door, RoHS and WEEE compliance, and included cable-routing hardware. It does not serve buyers who need floor-standing racks, outdoor-rated housings, or more than four adapter slots.

Questions about this item
Will the 12-inch high by 14-inch wide wall-mount cabinet fit above my existing patch panel?
The enclosure measures 12 inches high, 14 inches wide and 3.3 inches deep, so compare those dimensions to the clearance above your patch panel before mounting.
How can I confirm the splice tray is seated correctly after installation?
Open the locking front door and verify the tray sits on the built-in mounting stud with fibres routed through the supplied cable-management hardware and no pinch points on the pigtails.
Does the JPM402A-R3 ship with splice trays or only the mounting stud?
The box includes the cold-rolled steel cabinet, locking front door, wall-mount hardware, cable-routing accessories and the splice tray mounting stud; splice trays themselves are sold separately.
