Ultra-Gutter Guard Plus®

Guard high - flow curb inlets from silt, sediment and other contaminants

The Plus model of the Ultra-Gutter Guard is designed for curb inlets with high-flow volumes. Its unique, multi-dimensional outer filter combined with a rigid inner frame and support counterweight prevents debris and silt from clogging inlets, while keeping the unit upright and secure.

Key Features:

  • Modular, 3-foot, inner frames allow for compact transport and storage.
  • Counterweight inserts into inlet to keep unit upright and secure.  An optional 7 lb. weight available is available - rebar, gravel or other material can also be used.
  • Tie-back straps on either end of unit can be used with sod pin or stake for additional anchoring.
  • Can be easily cleaned and reused.
  • Sizing note:  When ordering allow 12" overlap on each side of curb inlet.
  • Helps comply with NPDES, 40 CFR 122.26 (1999) and TMDL requirements.
