Steel City RC Beam Clamp Conduit Hanger, Malleable Iron

Two sizes, 2 inch and 3 inch conduit, ordered as RC 2 SC and RC 3. The size refers to the conduit the hanger carries, not the beam flange, so match it to the run you are supporting. Each clamp is sold individually.

Two different jobs. The RC clamp grabs the beam flange and carries the conduit directly, which is what you want for a single run tight to the steel. If you need to drop below the structure, or hang a strut trapeze or multiple conduits, use a threaded-rod style clamp such as the Appleton IS-500, tapped 1/4-20, or the Kindorf FBC1 structural beam clamp for 1/4 inch-20 rod, then hang your support off the rod.

The Appleton IS-500 is also a malleable iron beam clamp, so it is the nearest material match to the Steel City RC. The difference is in how the two attach: the IS-500 is a screw-type clamp with a hexagonal head and a 1/4-20 tapped hole for hanging rod or fittings, while the Steel City RC is a conduit hanger style beam clamp sized to the conduit it carries, offered in 2 inch and 3 inch sizes.

No. The FBC1 is a structural beam clamp built to take 1/4 inch-20 threaded rod, so it gives you a rod attachment point at the beam. The Steel City RC 2 SC is a beam clamp conduit hanger sized at 2 inch, in malleable iron, which holds the conduit itself. They solve different parts of the support, and on many runs both get used together rather than one replacing the other.

The RC beam clamp is malleable iron with a galvanized finish, so it holds up in damp and unheated interior spaces better than a bare steel part. For direct outdoor weather exposure or corrosive wash-down areas, specify hardware rated for that service instead.

No drilling and no anchors. The RC clamp mounts by clamping onto the beam flange, which is the reason it gets used on exposed structural steel where you cannot or should not drill. It carries the conduit itself, so no rod, strut, or separate hanger is required for a single run.

The Kindorf FBC1 structural beam clamp is packaged 100 to a pack, which suits a repetitive hanger layout where one clamp per rod drop is being set. The Steel City RC beam clamp conduit hanger is sold by the each, which fits replacement and small-quantity work. Note the FBC1 is built for 1/4 inch-20 threaded rod, not for clamping conduit directly.

The Steel City RC beam clamp conduit hanger is malleable iron with a galvanized surface finish, which is the finish detail to point to on a damp or unconditioned space. Among the alternatives, the Appleton IS-500 is specified as a malleable iron beam clamp and the Kindorf FBC1 as a structural beam clamp, so confirm the finish you need on those separately before substituting.

The Steel City RC beam clamp conduit hanger, in malleable iron, carries a United States country of origin, which is the one to put on a bid with a domestic sourcing requirement. For the Appleton IS-500 and the Kindorf FBC1, verify origin against the order documentation before substituting on that type of contract.

Yes, country of origin is the United States. That matters on public and institutional work with domestic-content requirements, so keep the RC 2 SC or RC 3 part number on the submittal.
