Modern apartment buildings demand durable, well‑organized cluster mailboxes to handle mail delivery 

for multiple households.Today we showcase this bespoke multi‑compartment mailbox cabinet, 

custom‑built for a high‑rise residential complex. See our finished unit, functional test and 

detailed close‑ups of lock compartments.

Completed Custom Cluster Mailbox Cabinet

This heavy‑duty cluster mailbox is tailor‑made for a 10‑floor residential building.
Multiple individual mail compartments are arranged neatly, each fitted with independent lock and key. 

Laser‑cut numbering clearly marks every unit ID (0101‑1003). Floor indicator graphics “01F‑10F” are printed 

on the side panel for easy reference for residents and delivery staff.
Finished with bronze‑tone powder coating, paired with black side panels and base. The whole cabinet is built 

from robust metal material for long‑term indoor or semi‑outdoor residential use

Functional Opening & Lock Test

Before shipment, every compartment undergoes strict functional testing.
Multiple mailbox doors are opened to verify lock‑and‑key performance, check door swing and compartment inner space. 

Each lock works independently, ensuring every household gets secure private mail storage.
The cabinet’s side profile shows its solid thick‑wall structure, which resists deformation and enhances 

anti‑theft performance for multi‑family use.

Detailed Close‑Up Inspection
Detailed quality checks cover every corner: lock hardware, door fit, number marking, 

cabinet side and base construction.
Every lock, hinge and compartment is inspected one‑by‑one. Custom layout, compartment quantity, 

color finish, numbering and graphic marking are all configurable to match your building layout.
This unit is fully tested and ready for packaging and project delivery.

We provide full OEM & ODM service for residential cluster mailboxes: custom compartment count, 

dimension, color, numbering & branding.
All metal fabrication, powder coating, lock assembly and quality testing are completed in‑house in our factory. 

Ideal for apartments, condominiums and mixed‑use residential projects.
