Steel City RC-2SC – Frequently Asked Questions
1) Will the Thomas & Betts RC-2SC beam clamp work on a 2-inch beam flange?
That is exactly what the RC-2SC is sized for. It is a 2-inch beam clamp, meaning it jaws onto a structural steel flange in that size range and holds conduit supports or threaded rod without drilling or welding the beam. For a different flange width you need a different size in the Steel City beam clamp line, not this one.
2) Can I hang threaded rod from the RC-2SC beam clamp for a conduit run?
Yes. The RC-2SC is built to accept threaded support rod so you can suspend conduit, cable tray, or other electrical infrastructure from overhead structural steel. The usual assembly is clamp on the beam flange, rod down, then a hanger or strap at the conduit. Rod, nuts, and the conduit hanger are separate items.
3) Do I need to drill the beam or add anchors to install this clamp?
No. The clamp bites onto the beam flange itself, so there is no drilling, welding, or supplementary anchor hardware in the structure. That matters on projects where the structural engineer will not allow holes in the steel, and it is faster on retrofit work where you are adding conduit to an existing building.
4) What is a comparable malleable iron beam clamp to the Thomas & Betts RC-2SC?
The Appleton IS-500 is the closest malleable iron alternative. Both are malleable iron beam clamps for mounting to structural steel flanges; the RC-2SC is sized for 2-inch beam flange applications with a galvanized finish, while the IS-500 is a screw-type clamp with a hexagonal head and a 1/4-20 tapped hole for hanger rod or fastener attachment. If your support assembly is built around 1/4-20 hardware, the IS-500 states that thread directly; the RC-2SC is specified by beam size and galvanized corrosion protection.
5) I need beam clamps for a large conduit run on 1/4-20 threaded rod - is the RC-2SC the right pick or is there a better option?
For a high-count job running 1/4-20 threaded rod, the Kindorf FBC1 structural beam clamp is specified for 1/4-20 threaded rod and is supplied as a pack of 100, which suits repetitive overhead hanger work. The Thomas & Betts RC-2SC is a galvanized malleable iron clamp sized for 2-inch beam flange applications and is ordered as the single RC-2SC model, which suits jobs where the beam flange size and a corrosion-resistant finish drive the selection.
6) Is a galvanized malleable iron beam clamp OK for outdoor or damp locations?
The RC-2SC body is galvanized malleable iron, and the zinc coating is there to resist rust and corrosion in both indoor and outdoor environments. Malleable iron also resists cracking and bending under load better than a cast grey iron part, which is why it is the standard material for overhead support clamps. For severe chemical or coastal exposure, most specs call for stainless, not galvanized.
7) What part number do I order for the 2-inch Steel City beam clamp?
Order Thomas & Betts Steel City RC-2SC. That is the manufacturer part number for the 2-inch galvanized malleable iron beam clamp, and it is a single configuration, so there are no finish or thread options to pick on top of it.
8) Is the Kindorf FBC1 the same thing as the Thomas & Betts RC-2SC beam clamp?
No. Both attach to structural steel beams, but they are different parts. The RC-2SC is a Steel City galvanized malleable iron clamp specified by a 2-inch beam size. The Kindorf FBC1 is a structural beam clamp specified by its 1/4-20 threaded rod attachment and sold in 100-piece packs rather than as a single part. Confirm which spec your drawing calls out - beam flange size or rod thread - before swapping one for the other.
9) Which beam clamp should I use outdoors or in a damp industrial area?
The Thomas & Betts RC-2SC carries a galvanized finish over its malleable iron body, which is the corrosion-protective option among comparable clamps - the Appleton IS-500 is described as malleable iron with a screw-type hexagonal head without a stated protective coating. For exterior or washdown-adjacent conduit support on structural steel, the galvanized RC-2SC is the straightforward choice.
10) Can facilities buy this for standardizing conduit support in an industrial plant?
It is aimed squarely at commercial, industrial, and institutional conduit and raceway support, both new construction and retrofit. Standardizing on one clamp size only works if the steel in your building actually has a consistent flange; mixed framing usually needs two or three sizes from the same Steel City beam clamp family. The RC-2SC is made in the United States.
