Two-Gang Deep Electrical Box

The KILLARK 2FDC-2 is a two-gang aluminum device box designed for electrical installations requiring extra wiring capacity. Its 50 cu in volume accommodates multiple conductors and devices in commercial or industrial settings. The gray finish provides corrosion resistance for indoor or outdoor use.

Internal Grounding and Tapered Hubs

An internal grounding screw simplifies bonding without separate hardware. Two 3/4 in tapered-thread hubs accept conduit directly, creating a secure mechanical and electrical connection. Lug brackets allow surface mounting on walls or structures.

Surface Mount with Lug Brackets

The box mounts via lug brackets with holes on 0.75 in centers, aligning with standard framing or channel. Installers must ensure conduit threads engage fully in the tapered hubs to maintain grounding continuity. The 2.93 in depth requires adequate cavity space behind the mounting surface.

Questions about this item

Will the internal grounding screw ever need replacement?

The internal grounding screw is built into the aluminum box and is not a wear item; it does not require periodic replacement.

What capacity limit is reached first when adding conductors to this 50 cu in box?

The 50 cu in volume rating is the limiting factor; conductor fill must not exceed this capacity.

Does the aluminum housing run hot when circuits are live all day?

Aluminum dissipates heat well; the box itself does not generate heat and stays at ambient temperature during continuous use.
