4C Custom Horizontal Mailboxes - Front or Rear Loading
Following simple guidelines, custom units can be configured with a combination of varying sizes of mailbox doors and parcel locker doors.
1) Determine the number of openings required using MB1, MB2, MB3 and MB4 mailbox doors and PL3, PL4, PL4.5, PL5 and PL6 parcel locker doors.
Note 1: MB1 is the smallest mailbox door available and MB4 is the largest mailbox door available.
Note 2: PL3 is the smallest parcel locker door available and PL6 is the largest parcel locker door available.
2) Configure your requirements into a double or single column unit:
Note 1: Single or double column units can be configured from a minimum of three (3) standard one high mailbox doors to a maximum of fifteen (15) standard one high mailbox doors including both mailboxes and parcel lockers.
Note 2: Mailboxes are only permitted in the top eleven (11) one high mailbox positions. Parcel lockers may be positioned anywhere. 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. Parcel lockers are not required for installation sites with less than ten (10) tenant compartments.
Note 3: The outgoing mail compartment (OM2 and OM3) cannot be used for mail distribution and must be situated in the designated position. See our standard units
for illustrations of the designated position of the outgoing mail compartment (OM2 and OM3) in their respective heights.
Note 4: Tenant locks in the top row of mailboxes must be no more than 67" above the finished floor and the bottorm shelf of the lowest row of mailboxes must be no less than 28" above the finished floor. For front loading installations, the U.S.P.S. master arrow lock must be a minumum of 36" and a maximum of 48" above the finished floor. The bottom shelf of parcel lockers must be at least 15" above the finished floor.
