Industrial Floor Grate for Heavy-Duty Drainage

The Jr Smith B05NB is a nickel-bronze adjustable floor grate built for industrial plumbing systems. Its square profile and screw-in installation suit commercial floors that demand a flush, secure fit. The unit ships with mounting screws included.

Sustained Load Performance

Rated for a 2,000 lb load capacity under Load Class A, the grate maintains structural integrity under continuous foot and light vehicle traffic. The solid nickel-bronze construction resists corrosion and deformation over long service periods without requiring periodic re-torquing.

Replaces Basic Cast-Iron or Plastic Covers

This grate upgrades from standard non-adjustable covers that cannot align with finished floor heights. The adjustable frame eliminates the need for shims or mortar beds during retrofit or new construction. It is not suited for ADA-compliant projects or applications requiring heel-proof slot patterns.

Questions about this item

How much heat does the B05NB grate generate when it is running all day?

The B05NB grate is a passive floor fitting with no power supply or moving parts, so it produces no heat during continuous use.

What existing plumbing must I already have for the B05NB grate to install?

The B05NB grate fits a floor drain with a 3-3/4 inch pipe diameter and a square drain style, and it includes the mounting screws.

Will the B05NB grate work with the older floor drain body I am keeping?

The B05NB grate is designed for a 3-3/4 inch pipe diameter and square drain style; if your existing drain body matches those dimensions it will fit.
