Mailboxes for Dormitories

Horizontal mailboxes are a great choice if you need a large number of mailboxes for your student dormitories.

Choose from available base mailbox models or build a custom horizontal mailbox system.

4C Horizontal University Mailboxes

4C horizontal mailboxes are a popular horizontal choice for university settings due to their modular nature and secure parcel lockers.

All of our 4C mailboxes are wall-mounted, front-loaded only, and available in 8 different color options.
