Value Collection 10503120 Galvanized Duct Stack Elbow

Product Description

The VALUE COLLECTION 10503120 is a galvanized steel shortway 90-degree stack elbow designed for use in sheet metal duct systems. This fitting makes a 90-degree directional change in a compact profile, routing airflow from a main trunk or plenum into a vertical stack. The inside diameter measures 3.25 inches and the fitting runs 12 inches in overall length. Standard gauge galvanized construction provides corrosion resistance and the rigidity needed for reliable, long-term duct connections. HVAC sheet metal installers and duct fabricators use this fitting in forced-air residential and light commercial applications.

This stack elbow is suited for trunk-to-stack transitions in forced-air heating and cooling duct systems. The shortway design minimizes the space required at the elbow turn, making it well suited for tight framing cavities and between-joist runs. At 4.25 inches wide and 4.5 inches tall at the elbow, the fitting works in standard stud or joist bay duct layouts. It is sold individually and is a straightforward replacement or new-installation fitting for galvanized rectangular-to-round duct configurations.

Key Features

• Shortway 90-degree stack elbow geometry for compact directional transitions
• 3.25-inch inside diameter fits standard round duct collars and boots
• 12-inch overall length suits typical stack runs in residential framing
• Galvanized steel construction resists corrosion in conditioned-air environments
• Standard gauge sheet metal for consistent fit with matching duct components
• Single-piece construction with no assembly required

Compatibility

Designed as an OEM-style sheet metal fitting for use in standard galvanized forced-air duct systems requiring a 3.25-inch inside diameter shortway 90-degree stack elbow connection.

Installation Notes

Installation is performed by licensed HVAC technicians or qualified sheet metal workers. Power down the air handler or furnace before making any duct connections. Secure the fitting to adjoining duct sections with sheet metal screws and seal all joints with UL 181-listed foil tape or mastic sealant in accordance with local mechanical codes. Avoid over-crimping the collar, as deformation can restrict airflow and compromise the seal.
