2-Hole Drain Sump(Series B1)

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 for a seamless appearance while providing reliable debris capture and drainage control. UV-resistant polymer construction ensures durability in outdoor conditions and medium-duty traffic areas. The high-capacity chamber helps keep downstream drain lines cleaner, and the removable grate allows easy maintenance. Multiple sumps can be linked to support larger drainage systems.
