TDS 461D Class E Slotted Ductile Iron 122mm x 500mm Grate

SKU: 461D

Heavy Duty Ductile Iron Slotted Class E (122mm x 498 mm)


Universal Ductile Iron Slotted (Class E)  grate that works with 100 mm wide trench drain systems. If you need to replace a ductile iron slotted grate for your ACO K100S, ABT PolyDrain, MEA J1000 or ULMA U100K trench drain system, look no further. TDS has introduced a universal trench grate that fits all these systems.

The 461D grate is the perfect replacement grate for the now obsolete MEArin 152411 slotted ductile iron grate.

This grate is 498mm long, 122mm wide, 19.05mm high and has a center hole for a bolt and toggle channel locking.  Thicker ribs under the cross bars enable this grate to handle traffic with a Class E load rating.  Each grate is coated with a black epoxy paint and weighs 13.2 lbs.

Locking devices sold separately.
