HUBBELL KILLARK FS-2M Electrical Box

This HUBBELL KILLARK FS-2M is a weatherproof electrical box designed for conduit wiring installations. It provides a single-gang enclosure with a capacity of 18 cu in. The iron construction offers durability for demanding environments. It carries CSA and UL Listed certifications for safety compliance.

Suits single-gang conduit runs needing weather

Electricians running exposed conduit in wet or damp locations will find the lugged bracket and gray iron body appropriate. Installations requiring non-metallic enclosures or larger multi-gang configurations should consider alternative box types. Projects needing integrated cable clamps must verify compatibility separately.

18 cu in capacity handles standard device wiring

The internal volume accommodates typical conductors and a single switch or receptacle with pigtails. Box fill calculations must respect the 18 cu in limit for the specific wire gauge and device count used. Complex splices or high conductor counts may exceed the available space.

Questions about this item

What conduit size fits the lugs on this FS-2M box?

The box uses lug brackets for mounting; conduit size is determined by the separate hubs or fittings you choose to thread into the FS-type openings.

Can I mount this 18 cu in iron box on a wooden stud wall?

Yes, the lug brackets allow direct fastening to wood or metal framing, and the iron body provides the required grounding path when used with a grounding screw or clip.

How do I confirm the box meets code after installation?

Verify the UL and CSA markings are visible, ensure the 18 cu in capacity matches your conductor fill calculation, and check that the gray iron body is securely grounded.
