Southwark Metal 59FUDD4106 Drywall Ceiling Register Boot

Product Description

The SOUTHWARK METAL 59FUDD4106 is a double-lip drywall ceiling register boot designed for residential and light commercial HVAC duct distribution systems. Part of the 59FUDD series, this boot connects a 4-inch round duct to a 10 x 6 inch ceiling opening, transitioning supply airflow from round ductwork to a flush drywall ceiling application. The double-lip design seats against the drywall face for a clean, finished look without requiring additional trim. HVAC installers use this boot when running supply runs to drywall ceilings where a round-to-register transition is needed at the terminal end of the duct branch.

This boot is suited for new construction and renovation projects where supply air outlets terminate at drywall ceilings. The 4-inch collar accepts standard round flexible or rigid ductwork commonly used in residential forced-air systems. The 10 x 6 inch face opening accommodates standard 10 x 6 register grilles. This fitting is typically installed by HVAC sheet metal mechanics and duct installers working on forced-air heating and cooling systems in single-family homes, multifamily units, and light commercial spaces.

Installation Notes

Installation is performed by licensed HVAC technicians or qualified sheet metal mechanics. Shut down and lock out the air handling system before connecting ductwork at the boot collar.

Ensure the drywall opening is cut to the correct dimension before setting the boot to achieve proper lip contact and an airtight fit.
