  • Choose between open style and lock style cabinets according to your security needs
  • The front cover extends past the connector field on the user side of the panel, providing full patch cord protection
  • Separate front covers provide access to both the users’ side and the technician’s side, which is lockable
  • 1-year Double Diamond Protection
  • Allows you to easily interconnect to active equipment or patch vertical or horizontal runs


The open style enclosures can be mounted almost anywhere, and allow you to interconnect to active equipment or patch vertical/horizontal runs.

Lock style cabinets are ideal for secure fiber connections. They provide full frontal access to pigtails and connectors as well as a splice tray mounting stud. These fiber enclosures come unloaded, so you can snap-in up to 4 to 12 adapter panels.


Some more interesting features of these Fiber Wall Cabinets are:

  1. If you need to access the cabinets from the rear, just fold open the rear door. Thumbscrews hold it in place.
  2. Each side of the enclosure has a large access opening for routing cables horizontally
  3. The fiber cabinet comes with front or center adjustable brackets for easy mounting in other cabinets or racks
  4. The inner tray pulls out for easy access to the adapter panel that you install in the unloaded enclosure. A screw-lock safety catch keeps you from pulling out the tray too far
  5. Four rubber grommet openings enable you to route fiber cable through the top of the enclosure. Four additional openings are also provided on the bottom
  6. You can use the interior cable ties and black spool rings to hold distribution cables in place. The spool also provides storage for excess cable lengths
  7. Multi-pair fiber optic cable terminates in the snap-in adapter panels
  8. Rectangle cable holders also snap into the tray
  9. The fold down front door has a smoked plastic front cover that enables you to view cable terminations when it is closed
