Seal-tite WK38-25X10RAB Return Air Box 25x10 in

Product Description

The SEAL-TITE WK38-25X10RAB is a return air box designed for residential and light commercial HVAC systems. It provides a structured, sealed transition point where return air is collected and directed back to the air handler or furnace. The unit accommodates a 25-inch by 10-inch duct opening, making it suitable for medium-capacity return air applications. Licensed HVAC technicians and sheet metal installers typically supply and fit this component during new construction or duct renovation work.

This return air box is used in forced-air HVAC systems where a dedicated return air pathway is required. It fits into wall, floor, or ceiling return air installations depending on system layout. The 25-inch by 10-inch duct opening aligns with common residential and light commercial duct sizes used in single-zone and multi-zone forced-air configurations.
