mailbox compartments have open backs and are constructed of all aluminum. Color is silver

RACK LADDER SYSTEM
Rack ladder system mailbox units are designed to be installed between rack ladders. The
rack ladders support five (5) mailbox units to form a column of mailboxes. The first
column of mailbox units requires two (2) rack ladders and each additional column in the
same configuration requires another rack ladder. These units have the same outside
dimensions regardless of individual door sizes.
