ABSTRACT:
A Chicago-style plenum-type electrical junction box provides an air impermeable barrier between a box support structure and a junction enclosure. The junction box includes a base plate and a peripheral wall, the peripheral wall extending from the base plate such that the base plate and peripheral wall define the junction enclosure. The base plate preferably includes a series of fastener knockouts so as to provide an air impermeable barrier. The fastener knockouts are selectively removable for exposing a series of fastener-receiving apertures. The fastener-receiving apertures receive a series of fasteners for sealing the fastener-receiving apertures when fastening the junction box to the box support structure thereby providing an air tight barrier between the box support structure and the junction enclosure.
