Seal-tite 1374-031207 90 Degree Angle Boot 3x12 in

Product Description

The SEAL-TITE 1374-031207 is a 90-degree angle duct boot designed for transitioning airflow from a duct run to a floor, wall, or ceiling register. Measuring 3 inches by 12 inches with a 7-inch depth and a 2-inch extension, this boot provides the geometry needed to make clean directional changes in residential and light commercial duct systems. HVAC technicians use this fitting where a straight boot will not fit the framing cavity or where additional reach is needed to land flush at the register opening.

This boot is suited for new construction and retrofit duct installations where a 90-degree transition is required. The 2-inch extension adds clearance between the duct collar and the register face, which is useful in thicker floor or wall assemblies. It fits standard rectangular duct systems and is selected when the register or grille opening calls for a 3-inch by 12-inch face dimension.

Key Features

• 90-degree angle configuration for directional duct-to-register transitions
• 3 inches by 12 inches face opening to match standard register sizes
• 7-inch boot depth accommodates typical framing cavity clearances
• 2-inch extension provides additional reach for thicker wall or floor assemblies
• Designed for rectangular duct system connections in residential and light commercial applications

Compatibility

Designed as an OEM-style replacement or new-installation fitting for rectangular duct systems requiring a 3-inch by 12-inch 90-degree angle boot with a 2-inch extension.

Installation Notes

Installation is performed by licensed HVAC technicians or sheet metal contractors. Power down the air handling system before connecting or sealing any duct fittings. Seal all joints with mastic sealant or UL-listed foil tape in accordance with local mechanical codes and SMACNA guidelines. Secure the boot to the duct collar and framing as required to prevent movement or air leakage at the register connection point.
