Electrical box with 28 cu in capacity

The Killark FD-1M is a single-gang FD type electrical box designed for weatherproof installations. Its 28 cu in capacity provides space for wiring connections in commercial or industrial environments. The gray iron construction suits exposed locations where durability is required. It is UL Listed and CSA certified for code-compliant work.

Iron material handles thermal cycling

Gray iron dissipates heat from electrical connections without deforming under load. The metal body does not generate noise and draws no power itself. Lugs bracket mounting keeps the enclosure stable through temperature swings. No internal clamps are included, so installers supply their own cable securing method.

Lugs bracket fixes box to structure

The integrated lugs allow direct attachment to walls or poles without separate straps. Iron resists impact and corrosion in outdoor settings. Gray finish matches common conduit systems for a uniform appearance. Buyers who need a non-metallic enclosure or a box with built-in cable clamps should select a different model.

Questions about this item

How do I mount the FD-1M box using the lug bracket, and what step is often missed?

Secure the lug bracket to the mounting surface first, then attach the iron box; the step often missed is tightening the bracket fasteners before wiring so the 28 cu in cavity stays aligned.

What maintenance or replacement will the FD-1M iron box need over time?

Inspect the gray finish for corrosion and verify the lug bracket remains tight; replace the box if the iron shows rust penetration or the 28 cu in capacity is compromised by damage.

What limit appears first when the FD-1M box runs at full 28 cu in fill under sustained load?

Heat dissipation from the iron enclosure becomes the limiting factor; the gray iron walls can only shed so much heat before conductor insulation ratings are approached.
