Ultra-Drain Guard®

Adjustable Frame Model

Drain Guard stays in place even with grate removed

There are many models of Ultra-Drain Guard. And most of them are held in place by the weight of the storm drain grating. The one exception to this is the Adjustable Model. Instead, this unit relies on a steel framework to keep it from falling into the basin. 

The steel framework adjusts to fit different drain sizes. 

What is the advantage of this type of installation? For one thing, the Drain Guard remains in place even when the grating is lifted. With other models, crews need the foresight to secure the Drain Guard before lifting the grate. The other advantage is aesthetics. There is no excess material to trim or that may stick out above the grating. It's a clean and simple installation.

Key Features:  
  • Adjustable catch basin insert quickly re-sizes to fit almost any storm drain – no trimming of excess fabric required.
  • Steel frame adjusts and keeps Drain Guard in place – preventing it from falling into the basin even when the grate is lifted.
  • Heavy-duty hook-and-loop fasteners around the perimeter of the Drain Guard skirt keeps it secured to the frame.
  • Quick and clean installation – no measuring or trimming required.
  • The steel frame can be reused - Replacement Filter Fabric available and is quickly and easily installed.
  • Helps comply with NPDES, 40 CFR 122.26 (1999) and TMDL requirements.
