Southwark Metal 24_3-1/4X14X8 Duct Wall Stack Boot

Product Description

The SOUTHWARK METAL 24_3-1/4X14X8 is a 90-degree rectangular-to-round sheet metal duct wall stack elbow boot designed for residential and light commercial HVAC duct systems. Fabricated from hot-dipped galvanized steel, this boot transitions a 3-1/4 inch by 14 inch rectangular wall stack opening to an 8-inch round duct collar. The 90-degree elbow configuration makes it the standard choice for floor-to-wall or ceiling-to-wall transitions in forced-air supply duct layouts. HVAC sheet metal installers and duct fabricators use this fitting to terminate stub-out supply runs at registers and diffusers. Compliance with ACCA and SMACNA standards confirms the fitting meets recognized industry fabrication and performance benchmarks.

This wall stack elbow boot is suited for residential new construction and retrofit forced-air heating and cooling systems where space constraints require a 90-degree offset between the supply trunk or branch and the wall cavity stack. Typical installations include interior wall stack supplies feeding floor or baseboard registers. The rectangular inlet fits standard 3-1/4 inch by 14 inch wall cavity duct runs, while the 8-inch round outlet connects to flexible or rigid round duct. No specific model-family compatibility was stated in the product data.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal contractor. Shut down the air handling system and confirm the system is de-energized before cutting into existing ductwork or sealing new connections. Seal all joints with UL 181-listed duct mastic or approved metal foil tape per local mechanical code requirements. Follow SMACNA duct construction standards and applicable local codes for support spacing and fastener requirements.
