Box signs, which are also referred to as cabinet signs, are very common for businesses because the faces can be replaced easily, and you do not need to pull a permit to do so. New signs need a permit, but if you are only replacing the face, it does not count as a new sign, just an update. This is why you will see many box signs in shopping centers where the tenant may change. Many stores in shopping centers/strip malls are being rented, and it is not a permanent location.
We made this box sign from from aluminum, and the face is made from Tuf Glas and vinyl.
