Weatherproof Aluminum Box

The Killark FSC-2 is a single-gang electrical enclosure built from aluminum with a gray finish. It is intended for indoor or outdoor wiring junctions where moisture or dust resistance is required.

18 Cubic-Inch Capacity Limit

The box provides 18 cu in of internal volume, which caps the number and size of conductors that can be installed under code fill rules. Two opposing hubs accept conduit entries, and the lug brackets fix the unit to a mounting surface.

Conductor Fill And Device Space

The 18 cu in capacity comfortably handles a typical lighting junction or a single receptacle with a few conductors. It runs out when multiple large-gauge cables or a bulky device such as a GFCI receptacle are added, leaving insufficient free volume for safe installation.

It provides space for up to 18 cubic inches of conductors, devices and fittings so connections remain code-compliant and uncramped.

How do the two hubs and CSA/UL listing affect the installation?
