FleXstorm Catch-It: Temporary Inlet Protection

The FLEXSTORM CATCH-IT system is the preferred catch basin insert for temporary inlet protection, jobsite erosion control, and stormwater filtration.  FLEXSTORM CATCH-IT catch basin inserts fit any drainage structure: Curb Inlets, Round Inlets, Drop Inlets and Open throat Inlets are all easily protected with our patented design system.  FLEXSTORM Inlet Filter bags come with Woven fabric (FX) or Nonwoven fabric (IDOT) which effectively control eroded material from leaving the jobsite. Whether you are the specifier or the user it is clear to see how FLEXSTORM CATCH-IT Inlet Filters outperform the competition.

Watch FleXstorm perform during a major rain event.
