A wall outlet box having a plurality of walls defining an enclosure open at the front thereof is provided. The enclosure can include a back, opposing sides, a top, and a bottom. Forward facing edges of the enclosure can define a front periphery with a mounting lip extending therefrom for mounting the outlet box into a wall. At least one port is provided to engage with a dryer exhaust conduit and at least one measurement member extends from an edge of the port. The at least one measurement member can extend to at least a length approximately equal to a length of the protruding exhaust conduit sufficient to securely attach a flexible hose thereto, such that the exhaust conduit may be placed against the measurement member as a template prior to installation and cutting of the exhaust conduit and the outlet box.
