Learn More About Office Mail Slots

Office mail slots provide a practical way to receive letters, documents and internal mail through doors, walls, reception counters and partitions.

They are commonly used in office buildings, mailrooms, administration areas, schools, clinics and property management offices where a full mailbox or parcel box is unnecessary.

When selecting an office mail slot, consider the opening size, installation surface, wall or door thickness, flap structure, collection method and frequency of daily use.
