Questions about this item

How can I verify the Killark FS-1 box is correctly installed and safe to use?

After mounting, confirm the single hub aligns with your conduit entry, the internal volume measures 18 cu in for your wire count, and the gray aluminum body shows no damage; the UL and CSA listings indicate it meets safety standards when properly grounded and covered.

What components are included with the Killark FS-1 and what must I purchase separately?

The box itself is supplied as a single-gang FS-type aluminum enclosure with integral mounting lugs and one hub; you will need to buy a compatible cover, gasket, conduit fittings, and any required mounting hardware separately.

Which version of the Killark FS-1 should I choose for my wiring project?

This model is offered in a single 18 cu in capacity with one hub in gray aluminum; select it when your fill calculations require exactly that volume and a single conduit entry point.
