Black Box JPM402A-R3 Fiber Enclosure Wallmount Locking 4-Slot 12x14x3.3in

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.
