Introducing the 4C suite of mailboxes by Auth Florence, which strengthens security requirements for the entire unit. The new 4C series standardizes and improves tenant compartment lock design.

The mailbox is constructed of heavy gauge aluminum and 300 series stainless steel components for superior strength and exceptional outdoor durability. These rugged mailboxes have a corrosion resistant weatherproof powdercoat finish.

These units have a solid aluminum mail slot frame similar to the high security CBU design, which protects adjacent customer compartments and the collection compartment.

Each tenant compartment conforms to the new minimum size requirement of 12"W x 15"D x 3"H. New door sizes are now available giving you limitless options.

The 4C comes with either number decals, with up to three digits, or engraved identification, with up to six characters. The 4C introduces the parcel locker requirement based on a 1:10 parcel locker to tenant compartment ratio.

The surface mount collar allows you to mount your 4C Mailbox on a wall when you don't have the proper wall depth to recess them. The surface mount collar is constructed of heavy gauge aluminium and is comes powder coat finishes to match your 4C Mailboxes.

Mounting hardware is included for convenient, easy installation onto a conventionally constructed wood-stud wall. The fasteners are hidden for a clean, seamless look to your mail system.

The parcel lockers offer a unique double locking mechanism for added mail and package security. An optional mail slot plug to restrict access to mail slots is available. Call for details.
