20" wide ductile iron slotted trench drain grate
Ductile Iron Slotted Grate - natural finish - 20" wide x 24" long x 1.5" thick - rated for DIN load class F.
This is one of our strongest 20" wide trench drain grates. It is typically used on an 18" wide prefabricated trench drain or 18" wide catch basin. The larger openings plug less often making this grate ideal for the intake of large amounts of water. Typical uses are trench drains in airports, sea ports, industrial and manufacturing facilities, and any other area where extremely high loads are present.
