Southwark Metal USBR824342124 Unit Support Box R-8 Insulation 24 3/4 Inches X 21 Inches X 24 Inches

Product Description

The Southwark Metal USBR824342124 is a galvanized steel unit support box designed to provide a solid, insulated platform for HVAC air handling equipment in residential and light commercial installations. This unit support box features R-8 insulation and measures 24 3/4 inches wide by 21 inches long by 24 inches tall, making it well suited for standard rooftop and platform-mounted HVAC unit applications. Fabricated from 26-gauge hot-dipped galvanized steel per ASTM A653 CS Type B, this support box delivers reliable corrosion resistance and long-term structural durability in demanding installation environments. HVAC contractors, sheet metal installers, and mechanical contractors rely on unit support boxes like this one to properly elevate and support rooftop package units, air handlers, and other mechanical equipment above roof decks or structural surfaces. The 1-inch turned-in flange on all sides and the 1-inch flange turned up on three sides provide secure attachment points and help lock the box firmly in place during and after installation. All sides are beaded for added rigidity and strength, which is essential when supporting heavy HVAC equipment over time. The R-8 insulation is installed with adhesive and stick pins, providing thermal performance that helps reduce energy loss and condensation on the exterior of the support box. The galvanized coating on all surfaces ensures the box holds up against moisture, UV exposure, and the elements typically encountered on rooftop installations. Made in the USA, the USBR824342124 ships as a single unit and is ready to install straight out of the box. This model is ideal for jobs requiring a pre-insulated, heavy-duty unit support solution that meets commercial-grade quality standards.
