DUCT BOOT W/COLLAR 12″ X 8″ DBWC12X8

The DUCT BOOT WITH COLLAR 12″ x 8″ (DBWC12X8) is a heavy-duty, galvanized steel HVAC transition fitting engineered for high-performance airflow distribution. Designed to connect rectangular duct systems to round duct lines, this boot is an essential component for ensuring a smooth and efficient flow of air from a main trunk duct to a branch or register opening. The rectangular end measures 12 inches by 8 inches, making it well-suited for use in medium to large HVAC zones, whether in residential homes, commercial buildings, or light industrial applications.

What distinguishes this model is the pre-installed round collar, typically 6 to 8 inches in diameter, which provides a secure, efficient connection point for round ducting—either rigid or flexible. This collar helps reduce installation time and improves overall duct system performance by minimizing air leakage when properly sealed with HVAC foil tape, mastic, or clamps.

Built from premium galvanized steel, this duct boot offers exceptional durability, corrosion resistance, and structural strength, making it suitable for demanding environments, including attics, crawlspaces, or areas exposed to moisture. The flanged edges around the rectangular face offer easy alignment and fast installation—the flange can be screwed or nailed directly to subfloors, wall studs, or framing members, ensuring a snug and secure fit.

This model is ideal for transitions behind floor registers, wall vents, or ceiling grilles, and it ensures that conditioned air is delivered precisely and efficiently to the desired zone. Whether you’re installing new ductwork or upgrading an existing system, the DBWC12X8 provides a reliable, code-compliant solution that supports efficient airflow and thermal comfort.
