Zurn Z125 - 8-3/8" Diameter Roof Drain with Low Silhouette Dome

The Zurn Z125 is an 8-3/8-inch diameter roof drain built for reliable, high‐capacity performance in commercial roofing applications. Its compact size, rugged build, and protective features make it ideal for flat or low-slope roofs where efficient drainage, debris protection, and membrane security are essential.

Key Features
