Acid-Resistant Cast Iron Floor Drain

The Jay R. Smith Mfg. Co 3420G-13 is a square cast iron floor drain built for commercial and industrial settings where chemical exposure is a concern. Its acid-resistant finish protects the iron substrate from corrosive spills and cleaning agents common in laboratories or food processing areas. The drop-in design suits both new construction and retrofit projects. Contractors specify this model when drainage must withstand harsh environments.

2,000 lb Load Capacity Grate

The partial-opening grate supports a 2,000 lb load capacity, making it the decisive specification for vehicle traffic or heavy rolling equipment. This rating confirms suitability for forklift aisles, garage bays or loading docks where point loads are extreme. The grate is included as a replacement component, simplifying maintenance when the original wears. Buyers needing higher load ratings or ADA-compliant heel-proof openings must select a different drain model.

Passive Drainage With No Power Draw

The drain operates entirely by gravity, so it adds zero electrical load, produces no fan noise and generates no heat during normal use. The 1 1/4 in overall height keeps the profile low while the bottom outlet connects directly to standard waste piping. Acid resistance is inherent to the coating, requiring no powered cathodic protection or chemical dosing systems. Maintenance consists of periodic grate removal for sediment clearing.

Questions about this item

What does the 2,000 lb load capacity mean for everyday use?

The grate is rated to support 2,000 lb, so it handles heavy foot traffic, carts and equipment without bending or cracking.

How does the drop-in installation method work with the existing drain body?

The square grate sits inside a standard floor drain body; the 9 3/4 in overall width and length must match the frame opening for a secure fit.

What clearance is needed above the pipe for the 1 1/4 in overall height?

Only 1 1/4 in of vertical space is required above the drain outlet, making it suitable for shallow concrete pours or retrofit slabs.
