Atco Rubber Products 1240_12X12 Sheet Metal Duct Elbow 12x12

Product Description

The ATCO RUBBER PRODUCTS 1240_12X12 is a shortway sheet metal trunk duct elbow designed for vertical airflow direction changes in forced-air HVAC duct systems. Measuring 12 inches on both the inlet and outlet faces, this vertical elbow features rounded inside and outside throats that reduce turbulence and improve airflow efficiency through the fitting. It is fabricated from sheet metal and is suited for installation by licensed HVAC technicians working on residential and light commercial duct distribution systems.

This elbow is used where a trunk duct line requires a vertical directional change. The shortway geometry keeps the turn tight, making it practical in installations with limited ceiling or plenum clearance. Both the A and B face dimensions measure 12 inches by 12 inches, allowing it to mate directly with matching square trunk duct sections without requiring a transition fitting. HVAC installers will find it appropriate for new construction duct runs as well as replacement work in existing forced-air systems.

Key Features

• Vertical elbow orientation for up or down duct direction changes
• Rounded inside and outside throats reduce airflow restriction and turbulence
• Uniform 12 x 12 inch face dimensions on both inlet and outlet (Size A and Size B)
• Shortway design minimizes duct space required for the turn
• Sheet metal construction for durability in standard HVAC duct applications

Compatibility

Designed as an OEM-style replacement and new-construction fitting for standard 12 x 12 inch sheet metal trunk duct systems in residential and light commercial forced-air HVAC installations.

Installation Notes

Installation should be performed by a qualified HVAC technician in accordance with applicable mechanical codes, including SMACNA duct construction standards. Power down the air handling unit and verify the system is de-energized before modifying or connecting ductwork. Seal all joints with listed duct sealant or approved foil tape to meet local energy code requirements. Proper support of the duct run should be maintained per applicable codes to prevent stress on the fitting connections.
