Gray malleable iron two-gang electrical box with two 3/4-inch hubs, lug brackets and internal grounding screw

Hubbell Incorporated

Hubbell Incorporated KILLARK 2FDC-2M Electrical Box 3/4" Hub 50 cu in

SKU CH-Q64A-PGHEW

A two-gang malleable iron device box with two 3/4 in hubs and 50 cu in capacity, featuring internal grounding and CSA/UL listing

  • Product typeElectrical Boxes
  • Two-gang layout fits two devices
  • 50 cu in capacity handles more conductors
  • 3/4 in hub accepts standard conduit
  • Malleable iron body resists impact
  • CSA and UL listed for code compliance

Two-Gang Device Box for Industrial Wiring

This malleable iron device box provides two gangs and two inlets for conduit connections in demanding environments. It suits electricians and maintenance teams running branch circuits through hazardous or wet locations where metallic enclosures are required.

Thermal and Power Characteristics in Service

The iron body dissipates heat from conductors naturally without active cooling, so it adds no acoustic noise to the installation. Power draw is determined solely by the circuits pulled through the box, not by the enclosure itself.

Malleable Iron Construction with Tapered Hubs

Gray malleable iron resists impact and corrosion while the 3/4 inch tapered threads seal tightly against conduit. Lug brackets and 0.75 inch on-center mounting holes allow secure surface attachment, and an internal grounding screw simplifies bonding. The 50 cubic inch capacity meets code for the conductor counts typical in two-gang applications.

Questions about this item

How do I install the 3/4" hub on the KILLARK 2FDC-2M box, and what step is often missed?

Thread the 3/4" hub into the tapered threads using a wrench until snug; the step often missed is tightening the internal grounding screw to bond the conduit to the box.

What maintenance or replacement will the 2FDC-2M need over time?

Inspect the malleable iron body and gray finish periodically for corrosion; replace the box if the 50 cu in capacity is exceeded by added conductors or if mounting lugs crack.

What limit appears first when the 2FDC-2M runs at full 50 cu in fill?

Heat dissipation becomes the limiting factor; the 2.93 in depth and 4.56 in square footprint restrict airflow, so conductor temperature rises before the 50.0 cu in volume is reached.
