The UltraTech 8938 Drain Guard Economy Frame Model is an adjustable catch basin insert designed to capture sediment, debris, oil, and hydrocarbons from stormwater runoff before contaminants enter drainage systems. Its expandable metal frame adjusts to fit drain openings ranging from 16" x 20" to 28" x 36", reducing the need for multiple drain guard sizes across a facility. This version does not include overflow ports, providing maximum filtration area while retaining sediment, dirt, and other pollutants within the catch basin.
