The 16 gauge high security user drop box 3 (UDB3) provides physical security for single or multiple network connections and was designed specifically for use with Holocom Secure Mini Dukt. The UDB3 mounts securely on walls and restricts access to the cable termination point. The UDB3 top opening perfectly positions Secure Mini Dukt for a one-inch standoff using Holocom secure raceway spacers (SDS-RW-SPR-WT and in attachment Kits SDS-RW-AKT03). Built-in back plate or cable manager and manufactured mounting points provide additional installation efficiency. The door locks securely using Holocoms patented locking system and a Sargent and Greenleaf padlock.
