Height after installation: Must place the box's bottom 41 to 45 inches above the road and its front 6 to 8 inches behind the curb Out-of-range placement can stop delivery.
Box compatibility: Mounting arm or plate must fit your box type (standard T1, large T2 or a specific locking box) Not every post accepts every mailbox footprint.
