Southwark Metal 59fudd8148 90 Degree Ceiling Boot 8x14x8

Product Description

The SOUTHWARK METAL 59fudd8148 is a 90-degree ceiling boot with an outboard double drywall flange, designed for residential and light commercial HVAC duct systems. This fitting transitions airflow from a vertical duct run to a horizontal ceiling register opening, making it a standard component in forced-air supply distribution. The unit ships as a complete UL-approved assembly, which simplifies inspection and confirms it meets fire and safety standards at the point of installation. It measures 8 inches by 14 inches by 8 inches, fitting common residential supply trunk and branch layouts. HVAC sheet metal installers and mechanical contractors work with this type of fitting on new construction and retrofit duct jobs.

This ceiling boot is suited for supply air distribution in residential and light commercial forced-air systems. The outboard double drywall flange seats flush against finished ceiling surfaces, making it appropriate for drywall ceiling applications where a clean register border is required. The 8-inch by 14-inch face opening accommodates standard rectangular register grilles of that size. It is typically installed during rough-in on new builds or during duct modification work in existing structures.
