Single Vertical Boxes

SINGLE EXHAUST BOX

A popular model that works well as a single vent for dryer, kitchen or bathroom exhaust. Duct holes available in 4 inches (10.16 cm) or 6 inches (15.24 cm). What makes this model easy to install is the fact it works within the structural aspects of your project. This means it won't interfere with vertical reinforcement (Rebar) of the structure, because it's designed to fit in half of a CMU block (masonry unit or concrete block). We also offer different mounting options for exterior surfaces other than stucco, including brick and cladding.

MODEL#: 4SEB

A 4" (10.16 cm) duct vents exhaust, while a gravity damper prevents back drafts of exterior air. The box cavity is designed as one molded piece. This eliminates the seam between the box and the louver--usually a source of water intrusion, which leads to mold and mildew.

MODEL#: 6SEB

A 6" (15.24 cm) duct vents exhaust, while a gravity damper prevents back drafts of exterior air. The box cavity is designed as one molded piece. This eliminates the seam between the box and the louver--usually a source of water intrusion, which leads to mold and mildew.
