4C Mailbox Configurations
Salsbury 4C Horizontal Mailbox Congurations
Note: 3700 series 4C standard horizontal
mailboxes and parcel lockers have
been U.S.P.S. approved and meet the
specifications of USPS-STD-4C and are
required for new construction and major
renovations.

These units do not meet U.S.P.S.
installation requirements and are for
private delivery only unless approved by
local postal authorities.
2
For private delivery, unless parcel locker
ratio exceeds requirement. U.S.P.S.
standard 4C requires a minimum of one
parcel locker for every ten (10) tenant
compartments. Parcel lockers must be
a minimum of 15” high (PL4.5, PL5 and
PL6) to meet the 1:10 ratio. Once this
ratio has been met, smaller parcel lockers
(PL3 and PL4) may also be added.
