Southwark Metal 24R_2-1/4X10X4 Pipe Boot Elbow 2-1/4x10x4

Product Description

The SOUTHWARK METAL 24R_2-1/4X10X4 is a hot-dip galvanized steel sheet metal pipe boot elbow designed to transition round duct to a floor or wall register in residential and light commercial HVAC systems. The 90-degree elbow configuration allows duct runs to turn and terminate cleanly beneath registers without field fabrication. The boot measures 2-1/4 inches by 10 inches at the rectangular collar (Size A) and 4 inches in diameter at the round pipe connection (Size B). Licensed HVAC technicians and sheet metal contractors install this fitting as part of a forced-air supply or return duct system.

This pipe boot elbow is used in residential forced-air heating and cooling applications where a round duct must connect to a standard rectangular floor or wall register opening. The rectangular throat dimension of 2-1/4 inches by 10 inches matches standard register sizes, while the 4-inch round collar accepts 4-inch round pipe or flex duct. It is suited for new construction and retrofit installations where a clean, low-profile duct termination is required at the register box location.

Installation Notes

Installation should be performed by a licensed HVAC technician or sheet metal contractor. Power down the air handler or furnace and close any relevant gas or electrical supply before beginning duct work.
