Iron Weatherproof Box

The Killark FSC-1M is a single-gang electrical box built from iron for outdoor or damp-location wiring. It provides an 18 cu in capacity for conductors and splices in residential or light-commercial installations.

Check Mounting and Conduit Plan

Verify that the lug bracket suits your mounting surface and that the box depth fits the intended conduit entries. Confirm local code accepts the listed CSA and UL standards for the planned circuit.

Rugged Iron Construction

The gray iron body resists impact and corrosion in exposed environments. Lug brackets allow direct surface mounting without separate straps, while the 18 cu in volume gives room for neat wire arrangement and future maintenance access.

Questions about this item

Does the Killark FSC-1M box ship with a cover or must I buy one separately?

The box is sold as the FSC-1M enclosure only; covers are not included and must be purchased separately to complete the installation.

Should I choose the 18 cu in version or a larger capacity for my wiring job?

Select the 18 cu in model when your conductor count and device fill stay within that volume; move to a larger box only if the cubic-inch calculation for your circuit exceeds 18.

What does the 18 cu in rating mean once the box is mounted in a real wall?

It is the maximum internal volume allowed for conductors, clamps and devices under UL and CSA rules; your actual wire fill must not exceed this limit.
