Value Collection 10502120 Galvanized 90 Stack Elbow 2.25 in

Product Description

The VALUE COLLECTION 10502120 is a shortway 90-degree stack elbow fitting used in sheet metal duct systems for residential and light commercial HVAC installations. It features a 2.25-inch inside diameter and measures 12 inches in overall length, making it suited for tight-turn transitions in wall cavity stack applications. Constructed from standard-gauge galvanized steel, this fitting resists corrosion in typical indoor air distribution environments. HVAC installers and sheet metal contractors use this type of fitting to redirect airflow from a horizontal plenum or trunk into a vertical wall stack without requiring a longway elbow or additional offset fabrication.

This shortway 90-degree stack elbow is intended for use in forced-air duct systems where space constraints require a compact directional change. It is a common component in new construction and retrofit duct runs where a branch takeoff feeds a wall register through a floor cavity or interior partition. The 3.25-inch overall width and height dimensions allow it to fit within standard stud-bay framing. Sheet metal and HVAC technicians typically install this fitting as part of a supply-air distribution system serving a residential or light commercial forced-air unit.

Key Features

• Shortway 90-degree stack elbow geometry for compact directional transitions
• 2.25-inch inside diameter for branch duct connections
• 12-inch overall length for standard wall stack applications
• Standard-gauge galvanized steel construction for corrosion resistance
• 3.25-inch overall width and height fits within typical stud-bay framing

Compatibility

Designed as a standard-gauge galvanized replacement or new-installation fitting for residential and light commercial forced-air duct systems using 2.25-inch inside diameter stack connections.

Installation Notes

Installation is performed by licensed HVAC technicians or qualified sheet metal contractors. Shut down the air handling unit and verify the system is de-energized before modifying any duct section. Secure the fitting with sheet metal screws and seal all joints with UL 181-rated mastic or foil tape in accordance with applicable mechanical codes. Avoid sharp bends in flex connector transitions leading into or out of the elbow that could restrict airflow.
