Value Collection 10502100 Galvanized Stack Elbow 2.25 in

Product Description

The VALUE COLLECTION 10502100 is a galvanized steel shortway 90-degree stack elbow designed for rectangular-to-round duct transitions in residential and light commercial HVAC sheet metal work. This fitting connects trunk ducts to floor or wall stacks, redirecting airflow 90 degrees in a compact shortway profile. It measures 10 inches in overall length with a 2.25-inch inside diameter opening and overall dimensions of 3.25 inches wide by 3.25 inches tall. Constructed from standard-gauge galvanized steel, it resists corrosion in typical forced-air duct system environments. HVAC sheet metal installers and service technicians use this fitting during new construction and duct retrofit work.

This stack elbow is suited for residential forced-air heating and cooling duct systems where branch runouts connect a main trunk to a floor register boot or wall stack. The shortway 90-degree geometry is used in applications with limited clearance between the trunk duct and the finished floor or wall plane. The 2.25-inch ID opening matches standard small-capacity branch duct sizes common in residential supply-side distribution systems. It installs with standard sheet metal screws and duct sealant or UL-listed foil tape per local mechanical code requirements.

Key Features

• Shortway 90-degree geometry allows branch takeoff in tight clearance installations
• 2.25-inch inside diameter fits standard small-branch residential duct runouts
• Standard-gauge galvanized steel construction resists corrosion in conditioned-air duct systems
• 10-inch overall length provides adequate engagement with trunk duct collars and boot connections
• 3.25-inch by 3.25-inch profile keeps installation footprint compact within joist bays or wall cavities

Compatibility

Designed as an OEM-style replacement or new-installation fitting for residential forced-air duct systems requiring a shortway 90-degree stack elbow with a 2.25-inch inside diameter opening.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal installer in accordance with local mechanical codes and SMACNA duct construction standards. Power down the air handler or furnace and close the system before modifying duct sections. Secure all joints with sheet metal screws and seal with UL-listed foil tape or mastic duct sealant to prevent air leakage. Do not substitute flexible duct tape not rated for duct sealing applications.
