This stackhead connects a larger plenum or trunk opening to a smaller stack outlet, transitioning from a 14 x 20 inch face down to a 14 x 8 inch stack opening. It is designed for use in forced-air heating and cooling distribution systems where vertical wall stacks feed supply air to registers. Sheet metal contractors and HVAC installers work with this fitting during new construction and system retrofits.\u003c\/p\u003e\n\u003cp\u003eThis stackhead is suited for residential forced-air systems where a floor or wall stack feeds a supply register from a central trunk line. The 10L designation identifies it as part of a universal stackhead series, making it a common choice for standardized duct layouts. It fits into typical stud-bay stack installations where the duct transitions from a wider plenum face to a narrower wall stack run.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTransitions from a 14 x 20 inch opening to a 14 x 8 inch stack outlet\u003c\/li\u003e\n  \u003cli\u003eUniversal 10L stackhead design for standardized forced-air duct systems\u003c\/li\u003e\n  \u003cli\u003eEngineered for vertical wall stack supply air applications\u003c\/li\u003e\n  \u003cli\u003eFabricated by Southwark Metal, a recognized name in sheet metal duct components\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for residential and light commercial forced-air duct systems using standard 10L universal stackhead configurations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of this stackhead should be performed by a licensed sheet metal contractor or qualified HVAC technician.
