2-Hole Drain Sump(Series B4)

The Series B Drain Sump is a professional-grade catch basin for efficient surface water collection in landscape, hardscape, and drainage applications. Its low-profile design installs below grade to blend into surroundings while providing reliable debris capture and drainage control. Made from UV-resistant polymer, it withstands harsh outdoor conditions and medium-duty traffic. The high-capacity chamber helps keep downstream drains clear, and the removable grate allows easy maintenance. Multiple sumps can be linked for larger drainage systems.
