Florence vital™ 1570-16 Cluster Box Unit – 16 Tenant Mailboxes and 2 Parcel Lockers Type 3

The Florence vital™ 1570-16 Cluster Box Unit is a USPS-approved, pedestal-mounted centralized mailbox designed for secure outdoor mail and package delivery. It provides 16 tenant mailbox compartments, two integrated parcel lockers and one outgoing-mail compartment in a durable, freestanding enclosure.

Constructed from heavy-duty aluminum and stainless-steel components, the 1570-16 combines corrosion resistance, outdoor durability and convenient front-loading postal service. The matching pedestal is included, making it an excellent centralized-mail solution for residential communities, multifamily developments, commercial properties and other USPS-authorized installations.

Important USPS 1:5 Parcel-Locker Requirement

Current USPS guidance requires a minimum of one parcel locker for every five tenant mailbox compartments for applicable new or remodeled apartment-building installations.

This requirement may be written either way:

• 1:5 parcel-locker-to-mailbox ratio
• 5:1 mailbox-to-parcel-locker ratio

Both expressions mean the same thing: one parcel locker is required for every five tenant mailbox compartments.

Does One 1570-16 Meet the 1:5 Ratio by Itself?

The Florence 1570-16 includes:

• 16 tenant mailbox compartments
• 2 parcel lockers

For a project subject to the current USPS 1:5 requirement:

16 tenant compartments ÷ 5 = 3.2

Because a partial parcel locker cannot be installed, the project should generally be planned with at least four total parcel lockers. The 1570-16 provides two parcel lockers, so an installation consisting of only one 1570-16 would generally require two additional parcel lockers to reach four total parcel lockers.

Additional parcel capacity can be provided by adding a Florence valiant™ 1590 Series Outdoor Parcel Locker or by combining mailbox models that produce the required project-wide ratio.

The ratio is calculated across the complete mailbox installation—not necessarily on each individual CBU. Final equipment quantities, placement and installation must be reviewed and approved by the local USPS representative or Postmaster before ordering or construction.

How USPS Delivery Works

The 1570-16 is a front-loading Cluster Box Unit. A postal carrier opens the large master access door using a USPS-controlled arrow lock and can then service the tenant compartments, outgoing-mail compartment and parcel lockers from the front of the unit.

The CBU is manufactured with a preparation for the USPS arrow lock, but the arrow lock itself is controlled and installed by local postal officials. It is not supplied to the property owner as a regular customer-operated lock.

Tenant Mailbox Security

Each tenant mailbox door includes a heavy-duty cam lock and three tenant keys. The included tenant locks are individual locks; the tenant keys do not provide access to the postal carrier door or other tenant compartments.

The property owner or manager is responsible for distributing and tracking tenant keys and arranging replacement locks or keys when necessary.

Parcel-Locker Operation

When the postal carrier places a package in a parcel locker, the carrier uses the parcel-locker system to provide the appropriate tenant with access. Florence parcel-locker doors incorporate a double-locking mechanism designed to protect delivered packages.

The two parcel lockers are shared resources for the complete mailbox installation. They are not permanently assigned to specific tenant compartments.

Outgoing-Mail Collection

The built-in outgoing-mail compartment allows residents to deposit outgoing USPS mail. It includes:

• Mail-deposit slot
• Anti-fish comb for added security
• Protective hood
• Convenient placement above the USPS carrier access door

Outgoing mail is retrieved by the postal carrier during regular service.

Foundation and Installation Requirements

The CBU must be securely mounted to a properly designed concrete foundation using the manufacturer’s current foundation plan and installation instructions. The installation location must provide safe and unobstructed access for tenants and postal carriers.

Before ordering or pouring the concrete pad:

1. Contact the local Postmaster or USPS delivery-planning representative.
2. Confirm that centralized delivery is approved for the project.
3. Obtain approval for the mailbox location and equipment configuration.
4. Confirm the required tenant-to-parcel-locker ratio.
5. Review applicable accessibility and reach requirements.
6. Use the current Florence foundation drawing.
7. Verify clearance around the carrier and tenant sides of the unit.
8. Coordinate lighting, sidewalks, drainage and vehicle protection where required.

Do not prepare a foundation from website dimensions alone. Use the current Florence foundation plan and project-specific drawing.

Frequently Asked Questions

Is the Florence 1570-16 USPS approved?

Yes. Florence identifies the vital 1570-16 as a USPS-approved Cluster Box Unit and an officially licensed product of the United States Postal Service.

How many tenant mailboxes does it have?

The 1570-16 contains 16 standard tenant mailbox compartments.

How many parcel lockers are included?

It includes two parcel lockers: one approximately 9-7/8 inches high and one approximately 13-3/8 inches high.

Does the 1570-16 meet the USPS 1:5 parcel-locker ratio by itself?

Not for a project where all 16 tenant compartments are being counted under the current 1:5 requirement. Sixteen tenant compartments generally require at least four total parcel lockers. Because the 1570-16 includes two, the project would generally need two additional parcel lockers.

The ratio should be calculated across the entire approved mailbox installation and confirmed with the local USPS representative.

Is the ratio 1:5 or 5:1?

It depends on which item is stated first:

• One parcel locker for five tenant compartments is 1:5 parcel lockers to mailboxes.
• Five tenant compartments for one parcel locker is 5:1 mailboxes to parcel lockers.

Both describe the same requirement.

Can parcel lockers from another unit count toward the ratio?

The requirement is generally planned across the complete centralized-mail installation. Additional parcel lockers may be provided through other CBUs or separate Florence 1590 Series Outdoor Parcel Lockers. The complete layout must be approved by the local USPS representative.

Should I automatically order two additional parcel lockers with every 1570-16?

Not automatically. The number required depends on the total tenant compartments and total parcel lockers across the entire project. For example, a project containing different CBU models may already provide sufficient parcel capacity. Calculate the complete project and obtain USPS approval before ordering.

Is the pedestal included?

Yes. Florence states that the matching pedestal is included with the vital 1570 CBU.

Is the USPS arrow lock included?

No. The CBU is prepared for a USPS arrow lock. The arrow lock is controlled and installed by authorized local postal officials.

Can the owner purchase or install the USPS arrow lock?

No. The USPS arrow lock is postal property and is installed and controlled by authorized postal personnel. The property owner installs the mailbox equipment and coordinates final postal service with the local Post Office.

Are tenant locks included?

Yes. Each tenant door includes a heavy-duty cam lock.

How many tenant keys are included?

Florence supplies three keys with each tenant mailbox compartment.

Can all tenant compartments be opened with one tenant key?

No. Tenant compartments use individual cam locks. A tenant key is intended for its assigned compartment only.

Are the tenant doors already numbered?

Florence includes silver adhesive decals with black numbers 1 through 16 and parcel designations 1P and 2P. The decals are applied according to the approved numbering plan.

Is custom numbering available?

Custom identification or engraving may be available separately, but it should not be assumed to be included with the standard 1570-16.

Does the unit include outgoing mail?

Yes. It includes one outgoing-mail collection compartment with a deposit slot, protective hood and anti-fish comb.

Can outgoing packages be placed in the outgoing-mail compartment?

The outgoing compartment is intended for outgoing mail that fits through its deposit opening. It should not be described as an outgoing-package locker.

Can the 1570-16 be installed outdoors?

Yes. Florence designs the vital CBU for outdoor installation using heavy-duty aluminum, stainless-steel components and a durable powder-coated finish.

Is the unit waterproof?

Florence describes the construction as corrosion resistant and suitable for outdoor installations. It should not be described as waterproof or submersible. Proper site drainage and installation remain important.

Is a concrete pad required?

The pedestal-mounted CBU must be anchored to a properly prepared concrete foundation. Use Florence’s current foundation plan and installation manual before constructing the pad.

Are anchor bolts included?

Do not assume foundation anchors, concrete or site-preparation materials are included. Verify the current installation manual and order documentation before installation.

Can it be mounted directly into dirt, asphalt or pavers?

No. The pedestal must be properly anchored to a suitable concrete foundation designed according to Florence’s instructions and approved site conditions.

Can multiple 1570-16 units be installed together?

Yes. Florence CBUs can be used individually or grouped to serve larger developments. The total tenant count, parcel-locker count, clearances, accessibility and USPS approval must be evaluated for the complete installation.

Can the 1570-16 be used at an apartment building?

It may be used as part of an approved centralized-mail installation. The local USPS representative must approve the equipment, location and overall parcel-locker ratio. Do not assume that purchasing a USPS-approved mailbox automatically approves a particular project or location.

Can it be used for private delivery?

This model is designed and marketed as a USPS-approved CBU. Projects involving private delivery, non-USPS carriers or special access arrangements should be reviewed separately to ensure that the selected equipment and lock configuration are appropriate.

Does USPS approval mean USPS installs the mailbox?

No. The owner, developer or contractor is generally responsible for purchasing and installing the mailbox and foundation. USPS reviews the installation and installs the postal arrow lock when the installation is approved and ready for service.

Who determines the final mailbox location?

The property team should coordinate the location with the local Postmaster or USPS delivery-planning representative. Mailbox location, carrier access, tenant access and equipment configuration are subject to postal approval.

Does the 1570-16 automatically comply with ADA requirements?

Do not advertise the entire installation as automatically ADA compliant. Accessibility depends on the selected tenant-compartment assignments, approach, reach ranges, clear floor space, slopes and the complete site layout. Review the Florence height-layout drawing and applicable accessibility requirements.

What maintenance is required?

The owner should follow Florence’s maintenance and care instructions, keep the unit clean, promptly repair damaged doors or locks and maintain safe access around the equipment. USPS does not take ownership of the CBU merely because it installs the arrow lock.

Who is responsible for repairs?

The mailbox owner or property manager is generally responsible for maintenance and repairs to the equipment. Postal personnel control the arrow lock and postal access components.

What warranty does Florence provide?

Florence states that its equipment is covered by a five-year warranty from the shipment date against defects in materials and workmanship, subject to the manufacturer’s complete written warranty terms and exclusions.

Are decorative caps and pedestal covers included?

No. Decorative vogue™ accessories are separate options and should not be shown or described as included with the standard vital 1570-16.

What colors are available?

Florence lists Black, Dark Bronze, Forest Green, Postal Grey, Sandstone and White for the vital 1570 Series.
