Single-Gang FDC Box for Outdoor Wiring

The Killark FDC-1M is a one-gang weatherproof electrical box built for surface-mounted conduit runs in damp or wet locations. Its 28.5 cu in capacity suits residential and light-commercial circuits where a rugged enclosure is required.

Gray Iron Housing with Lug Mounting

Cast from iron and finished in gray, the box meets CSA and UL Listed standards for outdoor use. Integral lug brackets allow direct fastening to walls or poles, while the FDC form factor accepts standard covers and accessories for a secure, sealed installation.

Replaces Non-Weatherproof or Smaller Boxes

This unit upgrades from indoor-only enclosures or lower-capacity weatherproof boxes when conduit fill or environmental exposure demands more space and durability. The jump is worth it for new exterior circuits, service upgrades, or any retrofit where moisture resistance and code-compliant volume are essential.

Questions about this item

What does the CSA and UL listing mean for the FDC-1M box in practice?

The box meets Canadian Standards Association and Underwriters Laboratories safety requirements for use in wet or damp locations.

What mounting provision does the FDC-1M box use?

It uses integral mounting lugs cast into the iron body for direct surface attachment.

How do you install the FDC-1M box and what step is often missed?

Mount the box using the cast lugs, then thread on a compatible weatherproof cover and gasket; the missed step is torquing the cover screws to maintain the seal.
