1/4″ Cluster Box Units

C.B.U.s (Cluster Box Units)

Our CBUs (Cluster Box Units) are all custom and completely welded out of a 1/4″ steel frame with 3/16″ steel-reinforced doors. There are no rivets or spot welds, or parts that can be removed. The shell is over 3-4x thicker than the next heaviest duty CBU on the market! If you would like a quote, we need to know:

• Number of units?
• Number of tenants per unit?
• Need outgoing mail?
• Larger separate package compartments?
• In-Ground or Surface Mount (existing sidewalk) Post/Stand?
• Zip code for shipping?
• Is the location a residence or commercial address?
• If a commercial address, do you have a forklift or loading dock?

CBUs are heavy and the lightest box will be approximately 250 lbs., and go up from there. They also require front and rear door access — one side for the mail carrier and another for the tenants. You will need USPS approval for this setup.
