Everything is included with a cluster box unit purchased from U.S. Mail Supply, except for two items:
(1) USPS “Arrow” Locks – For security reasons the USPS does not allow the factory, or any non-USPS personnel to possess the master locks (also known as “Arrow Locks”), which are installed in the outgoing mailbox door, as well as each of the parcel locker doors. The local USPS will install this lock on these doors upon your request to do so. They typically do not charge for this service.
(2) Anchor Bolts for Mounting the Unit – The USPS has requested that we do not include the anchor bolts for mounting the unit to concrete due to varying frost lines throughout the United States. The factory recommends ½-inch diameter J-Bolts, with the length to be determined by the thickness of the concrete pad that is poured (most common pad depth is 5-6 inches). You will need four anchor bolts per unit, and they can be picked up at any local hardware store for a couple of dollars each. Please refer to the installation instructions that are shipped with the mailbox or view, print or download those instructions now.
Don't worry, we can help you figure out what's best and most cost efficient for your space. A representative at U.S. Mail Supply will help you figure out what is required for USPS or private delivery, the number of units you need and any information required for installation.
