An electrical box includes a first wall and a second wall spaced from the
first wall. A periphery wall joins the first and second walls and defines
a box volume therebetween. An opening formed in the first wall provides
access to the box volume. A collar extending outwardly from the first
wall. The collar defines a collar volume for receiving a device mounted
thereto. The box volume extends laterally beyond the collar to provide a
box volume independent of the opening.
