20" wide ADA wave pattern ductile iron trench drain grate
Ductile iron wave pattern grate - black - 20" wide x 24" long x 1.5" thick - rated for DIN load class C.
This 20" wide trench drain grate is used where the designer wants the trench drain to be aesthetically pleasing and still needs ADA compliance. This wave pattern grate also has significant inflow capability. It is typically used on an 18" wide prefabricated trench drain or 18" wide catch basin. The smaller openings are more prone to clogging than a slotted grate, but will provide adequate inflow when properly maintained. Typical uses are trench drains in combined traffic and pedestrian areas such as at shopping centers, churches, parks, pavilions, and any other area where high flow rates are required but the design cannot be compromised.
