An integral part of the installation, the universal plenum design can accommodate a range of different wall thickness (5” to 9”)

Two-piece design that allows assembling the plenum before installing in the wall by measuring the wall thickness to determine the right depth and reduces overall installation time

Plenum is easily installed from the interior of building. No need for exterior handling (*only caulking needs to be applied from exterior)

A 1.25" thick gasket assures a complete seal between the plenum and unit eliminating outdoor air or moisture from entering the space
