Order Exactly what you want.
Our CBUs are 100% custom order! Add Outgoing Mail Slots, Package receptacles, numbers...whatever you desire.
Our CBUs are all custom made 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!
Please visit our Construction Page to learn about why we're the best CBU you can choose for your neighborhood.
CBUs are very heavy and the lightest CBU will be approximately 250 lbs., and then go up from there. They also require front and rear door access — one side for the mail carrier and another for the tenants. All CBUs require USPS approval for setup. We've help so many people get exactly the CBU they want for their neighborhood.
