Conduit Hanger for EMT and RMC

The B-LINE BG812-S18 conduit hanger secures 1/2 in and 3/4 in EMT or rigid metal conduit to 4 in square boxes. It is made of steel with a zinc-plated black finish for corrosion resistance. Electrical contractors and maintenance teams use it for surface-mounted raceway runs in commercial and industrial wiring projects. It is not suited for larger trade sizes or non-metallic conduit types.

Screw Mounting on 4 in Square Boxes

The hanger attaches with screws directly to a 4 in square box, providing a fixed mounting point for the conduit. This mounting method decides whether the part fits the installer’s box and fastener preference. No clamp-on or bolt-on alternative is included, so the box must accept screw fasteners.

Steel Construction Under Continuous Load

The steel body and zinc-plated finish maintain structural integrity when supporting conduit over long horizontal or vertical runs. The 0.32 lb weight reflects a compact profile that adds minimal load to the box. UL and CUL listings confirm compliance with safety standards for sustained mechanical support.

Questions about this item

What does the 812 series designation mean when the hanger is installed on a 4 in square box?

The 812 series identifies this Eaton B-Line conduit hanger as designed to mount on 4 in square boxes using a screw, accepting both 1/2 in and 3/4 in EMT or RMC conduit.

How does the screw mounting type limit the load the zinc plated steel hanger can support?

Screw mounting secures the hanger directly to the box, so the load capacity depends on the box structure and fastener strength rather than a separate clamp mechanism.

What clearance does the 0.32 lb steel hanger need to fit 1/2 in and 3/4 in conduit on a 4 in square box?

The hanger mounts flush to the box with a screw, adding minimal profile while accommodating both 1/2 in and 3/4 in EMT or RMC conduit trade sizes.
