Dandy · Curb & Median Inlets · 4′

Dandy Curb sediment inlet filter in a 4′ length, for curb and median inlets without grates. The shortest length stocked, for compact curb openings. The unit sits against the opening, ballasted with aggregate, so flow is slowed and sediment is captured before it reaches the inlet.

01 Curb & median inlets without grates

The Dandy Curb Sediment Inlet Filter

An innovative curb inlet filter made especially for curb inlets and median inlets without grates — the openings that grate-mounted protection simply cannot address. It is designed to handle the worst that sludge-filled rainwater has to offer.

Rather than enclosing a grate, the Dandy Curb sediment inlet filter sits against the face of the opening, ballasted in place with aggregate. Flow is slowed and the sediment is easily captured by the unit prior to entering the inlet. Sediment does not stand a chance.

7lengths stocked · 4 to 16 feet

Sizes to fit any curb and inlet, with the unit centered so equal length overhangs each side of the opening.

02 Why it gets specified

Conforms To The Curb

A curb face is rarely as flat as a drawing suggests. The Dandy Curb is specially designed to quickly conform to the shape of the curb, and the aggregate-filled pouch creates a seal against the street surface — which is what stops flow slipping underneath instead of being filtered.

03 What you get

Get Maximum Benefits With Dandy

  • One-of-a-kind patented design keeps silt and debris out of storm systems
  • Specially designed to quickly conform to the shape of the curb
  • Built-in protective overflow design
  • Reduces or eliminates the need to flush or clean inlets, saving time and money
  • Easily seen because it is fabricated from a bright orange monofilament geotextile
  • Sizes to fit any curb and inlet
  • Available with optional oil absorbents
  • Easy to install, maintain, inspect and reuse
The overflow design is the detail worth understanding. A filter that blocks completely under a heavy storm becomes a flooding problem. The built-in overflow means the unit keeps filtering in normal conditions while still passing water when the rate exceeds what the geotextile can take.

04 Sizing

Available Lengths

Measure the inlet opening, then choose a length that leaves an equal overhang on each side. Seven lengths are stocked from 4 to 16 feet.

Allow for the overhang. The unit is centered against the opening with an equal length of Dandy Curb overhanging each side, so the length you need is the opening plus that overhang — not the opening alone.

05 Installation

Installation Guidelines

No grate to lift and nothing to dismantle. The unit is laid against the opening and ballasted with aggregate through a Velcro access pouch.

  1. Position the unit. Place the Dandy Curb on the ground with the aggregate pouch on the street side, near the inlet on which it will be installed.
  2. Open the access pouch. Open the Velcro access pouch located on the street side of the unit.
  3. Fit oil absorbents if using them. Place the sock in the pouch and push it back into the pouch.
  4. Fill with aggregate. Fill the pouch with aggregate to a level that will keep the unit in place during an event and create a seal between the Dandy Curb and the surface of the street.
  5. Reseal and center. Reseal the Velcro access, then center the unit against the curb or median inlet opening so there is an equal length of Dandy Curb overhanging each side of the opening.
The aggregate does the work

Two things depend on filling the pouch properly: the unit staying put during a storm event, and the seal against the street surface. Under-fill it and flow finds its way beneath the unit rather than through the geotextile, which defeats the installation entirely.

06 Maintenance

Keeping It Working

Inlet protection is only as good as its upkeep, and on an inspected site this is exactly what the inspector will be looking at.

  • After each storm event, remove all accumulated sediment and debris from the surface and vicinity of the unit.
  • If using oil absorbents, remove and replace the absorbents when they near saturation.

Because the unit is reusable, clearing sediment rather than replacing the filter is the normal maintenance action — which is where the running-cost advantage over disposable alternatives comes from.

08 Which Dandy do I need?

Grate Or No Grate

The Dandy Curb is for curb and median inlets without grates. If your inlet has a grate, the grate slides inside a bag instead — a Dandy Curb Bag for curb and gutter inlets, or a Dandy Bag for flat and round grates.

11 Common questions

Dandy Curb FAQs

What is the difference between the Dandy Curb and the Dandy Curb Bag?
The Dandy Curb is for curb and median inlets without grates — it sits against the opening and is ballasted with aggregate. The Dandy Curb Bag is for curb and gutter inlets that have a grate, which slides inside the bag. Match the product to the inlet you have.
What length do I need?
Measure the inlet opening, then add the overhang. The unit is centered so an equal length of Dandy Curb extends past each side of the opening, so the length required is the opening plus that overhang. Seven lengths are stocked from 4 to 16 feet.
What holds it in place?
Aggregate. A Velcro access pouch on the street side of the unit is filled with aggregate to a level that keeps the unit in place during a storm event and creates a seal against the street surface.
What happens if I under-fill the aggregate pouch?
Two things go wrong: the unit can move during an event, and the seal against the street is compromised so flow passes beneath the unit rather than through the geotextile. Filling the pouch properly is the single most important part of the install.
Will it flood the road in a heavy storm?
The unit has a built-in protective overflow design, so once flow exceeds what the geotextile can pass it overflows rather than damming completely. Keeping the unit clear of accumulated sediment is what preserves that capacity.
Does it work on an uneven curb?
Yes, that is part of the design. It is made to conform quickly to the shape of the curb, and the aggregate ballast pulls it down against the street surface to complete the seal.
Is there a minimum order?
No, there is no minimum order. Order any quantity, in any mix of the seven lengths.
How often does it need servicing?
Remove accumulated sediment and debris from the surface and vicinity of the unit after each storm event. If you are running oil absorbents, replace them as they near saturation.
Is it reusable?
Yes. It is designed to be installed, maintained, inspected and reused, which is where the cost advantage over disposable inlet protection shows up across a long project.
Can it capture oil as well as sediment?
With the optional oil absorbent sock fitted into the pouch, yes. Replace the absorbents as they near saturation.
What does shipping cost?
Nothing. Shipping is free on every order, at any quantity.
