Southwark Metal BHF12PL12X18X54 Plenum with Cap

Product Description

The SOUTHWARK METAL BHF12PL12X18X54 is a sheet metal plenum with cap designed for use in forced-air HVAC distribution systems. The plenum serves as the primary air distribution chamber, connecting the air handler or furnace to the supply duct network. Measuring 12.375 x 18.75 x 54 inches, this unit provides a defined internal volume for managing static pressure and airflow before distribution through branch ducts. The integrated cap simplifies installation by eliminating the need for a separate end closure. HVAC sheet metal mechanics and installers work with this component during new construction and equipment replacement projects.

This plenum with cap is suited for residential and light commercial forced-air installations where the equipment supply opening matches the plenum footprint. It fits above or adjacent to the air handler or furnace, transitioning into the main trunk line or branch duct layout. The unit is intended for indoor applications within conditioned or semiconditioned mechanical spaces. Installers should verify that the plenum dimensions align with the equipment collar and duct layout before ordering.
