The Southwark Metal 137ND23036 is a 30 inches by 36 inches galvanized steel drain pan designed for use beneath air handlers and furnaces with coils. It collects condensation before it can reach walls, ceilings, or flooring, helping HVAC technicians and installers protect structures from water damage. The pan measures 2 inches deep, giving it enough capacity to hold condensate during normal operation or in the event of a slow drain backup. It is built from 26 gauge hot-dipped galvanized steel, which resists rust and corrosion over years of continuous exposure to moisture. Folded corners add structural rigidity and help prevent leaks at the seams. A hemmed edge around the perimeter reinforces the pan and reduces the risk of sharp edges during handling and installation. This model carries the 137ND designation, meaning it ships without a pre-drilled drain connection. This no-drain configuration gives installers the flexibility to cut and fit a drain fitting at the location that best suits the job site layout. The pan is sold individually and is manufactured in the USA. It meets California Proposition 65 requirements. HVAC professionals working on residential and light commercial systems rely on secondary drain pans like this one to comply with local mechanical codes, which often require a secondary containment pan beneath any air handler or evaporator coil installed in a conditioned space or above a finished ceiling. The 137ND23036 is a straightforward, durable solution for condensate containment in split systems, package units, and other forced-air installations where an air handler or furnace with a coil is present.
The Southwark Metal 137ND23036 provides reliable condensate containment beneath air handlers and coil-equipped furnaces. Its 26 gauge hot-dipped galvanized steel construction and no-drain design give installers a durable, flexible secondary drain pan made in the USA.
