Drain Guards

Storm Drain Guards

A drain guard is a filter insert that hangs under a storm drain grate. Water keeps flowing into the drain while sediment, debris and oil get caught in the guard instead of washing into the storm sewer. They're a standard part of stormwater pollution prevention on construction sites, industrial yards, parking lots and fueling areas.

Drain guard types

  • Oil and Sediment models: catch silt and debris and absorb oil sheen. The Oil & Sediment Standard Model, Part #9219 is our most common pick, and the 10 Pack (Part #9218) covers a whole site.
  • Reusable models: a guard you empty and put back, in grate and curb style sizes like the 24" x 48" Reusable Model, Part #9342.
  • Adjustable frame models: a frame that fits a range of grate sizes, with round frames for round inlets and 10 packs of replacement filter fabric.
  • High capacity: the 60" x 60" Oil and Sediment model for large inlets.
  • Retainers: hold the guard in place in catch basins from 22" to 62".

How to pick a drain guard

Measure the grate opening, then decide what you're catching. Sediment only on a dirt site, oil and sediment where vehicles park or fuel. Check guards after every storm and replace or empty them once they load up, because a full guard stops filtering.

Stormwater items are usually in stock and arrive in about 7 to 10 business days. Buying for a whole site or a permit inspection? Request a quote and we'll price the full count.
