Southwark Metal 59FUDD4128 Double Drywall Ceiling Boot

Product Description

The SOUTHWARK METAL 59FUDD4128 is a double drywall ceiling register boot designed for residential and light commercial HVAC duct systems. This boot connects rectangular ductwork to a ceiling opening, providing a clean transition point for a drywall-flange register or grille installation. The 59FUDD series is built for flush drywall applications where the flange sits tight to the ceiling surface. Nominal dimensions are 4 inches by 12 inches by 8 inches, making it suited for standard residential supply air trunk-and-branch layouts. HVAC installers and sheet metal mechanics are the primary trades working with this component.

This boot is used in new construction and renovation projects where supply air outlets terminate at ceiling level. The double drywall flange design supports installations where drywall is applied after the ductwork rough-in, allowing the register face to sit flush with the finished ceiling. It fits into standard rectangular duct layouts commonly found in forced-air heating and cooling systems in residential single-family and multifamily construction.

Key Features

• Double drywall flange design for flush ceiling register installations
• Nominal 4 x 12 x 8 inch sizing suits standard residential supply air applications
• Part of the 59FUDD series for consistent compatibility within Southwark Metal product lines
• Rectangular duct connection supports trunk-and-branch forced-air system layouts

Compatibility

Designed as an OEM-style replacement or new-construction fitting for residential forced-air supply duct systems using rectangular ductwork terminating at ceiling-mounted register openings.

Installation Notes

This boot is installed by licensed HVAC technicians or sheet metal mechanics during duct rough-in, prior to drywall application. Power down the air handling unit and close the system before making any duct connections. Secure all duct joints with approved sheet metal screws and seal with mastic or UL-listed foil tape per local mechanical code requirements. Do not overtighten fasteners near the flange to avoid deforming the drywall seating surface.
