Whether your neighborhood has aging
mailboxes or if you are just tired of the snowplow
knocking over your curb-side mailbox, secure and
convenient cluster box units may be the solution.
Developed and approved by the USPS in 2005,
the new cluster box unit “F” specification became
the standard for all manufacturers and replaces
both the outdated Neighborhood Delivery
Collection Box Unit (NDCBU) and the “E” series
CBU. No longer permitted for replacement or
new installations, the original NDCBU introduced
convenience for residents and letter carriers alike,
but unfortunately these units are now falling into
disrepair as they have aged, and are in many
cases, quite dilapidated. The newer specifications
and thoroughly tested design requires more
stringent security features which help protect
your valuable mail and parcels better than any
previously available community mailbox. (see
images on opposite page.)
As these older units may have been in your
community for well over 20 years, it is the
Homeowners Association (or simply the residents
of the neighborhood) responsibility to maintain the
mailbox. Newer units have larger compartments
which lay the mail flat rather than rolling it, built
in parcel lockers, convenient outgoing mail slots,
and are significantly more secure.
