Southwark Metal 24R_2-1/4X10X5 Pipe Boot Elbow 2-1/4x10x5

Product Description

The SOUTHWARK METAL 24R_2-1/4X10X5 is a 90-degree sheet metal pipe boot elbow designed to transition from round duct to a floor or wall register opening. Constructed from hot dip galvanized steel, it provides durable corrosion resistance in residential and light commercial duct installations. The fitting measures 2.25 inches by 10 inches at the rectangular register face (Size A) and connects to a 5-inch diameter round duct collar (Size B). HVAC installers use this boot to make the final connection between branch ductwork and a supply air register in wood-framed floor or wall assemblies.

This boot elbow is suited for forced-air heating and cooling systems where a 90-degree offset is required between the round branch duct and the register face. It is commonly installed in residential new construction and retrofit applications where a 5-inch round branch duct feeds a 2.25-inch by 10-inch floor or wall register. The galvanized steel construction handles normal supply air temperatures without degradation. Fabrication meets ACCA and SMACNA applicable standards, making it appropriate for jobs that specify those guidelines.

Key Features

• 90-degree elbow geometry transitions round duct to a flat register opening in a single fitting
• Hot dip galvanized steel construction resists corrosion in conditioned-space duct applications
• 2.25-inch by 10-inch rectangular face (Size A) fits standard 2-1/4 x 10 floor and wall registers
• 5-inch diameter round collar (Size B) connects directly to 5-inch branch duct or flex duct
• Meets ACCA and SMACNA applicable fabrication standards

Compatibility

Designed as an OEM-style sheet metal fitting for forced-air duct systems requiring a 5-inch round to 2-1/4 inch by 10-inch rectangular register transition at a 90-degree offset.

Installation Notes

Installation is typically performed by a licensed HVAC technician or sheet metal mechanic. Power down the air handler and close the system before cutting into existing ductwork. Secure the boot collar to the branch duct with sheet metal screws and seal all joints with UL 181-rated mastic or foil tape per SMACNA and local mechanical code requirements. Do not install over active airflow or leave joints unsealed, as duct leakage reduces system efficiency and may cause pressure imbalance.
