Steel City RC-4SCHDG – Frequently Asked Questions
1) What conduit size does the Steel City RC-4 beam clamp support?
The RC-4 is the 4 inch conduit size in Steel City's RC beam clamp line. It supports a single run of 4 inch conduit off a structural beam flange. For smaller runs you need the corresponding smaller RC size, not this one.
2) Is the Steel City RC-4 beam clamp available in a galvanized version for outdoor or damp locations?
Two materials are offered: malleable iron (RC 4 SC) and hot-dip galvanized steel (RC-4SCHDG). The hot-dip galvanized version is the one to specify for exterior, wet, or corrosive runs; plain malleable iron is the indoor choice.
3) What is the difference between the Steel City RC-4 beam clamp and the Appleton IS-500?
The Steel City RC-4 SC is a beam clamp for supporting 4 inch conduit, made of malleable iron, with a hot-dip galvanized steel version also offered under part number RC-4SCHDG. The Appleton IS-500 is a malleable iron beam clamp with a screw-type hexagonal head and a 1/4-20 tapped hole, so it is set up to receive 1/4-20 threaded rod or a hanger rod rather than to clamp a conduit run directly. Choose the RC-4 when the clamp itself carries the 4 inch conduit, and the IS-500 when you are hanging from a rod off the beam flange.
4) Can I use a Kindorf FBC1 instead of a Steel City RC-4 to support 4 inch conduit?
They do different jobs. The Kindorf FBC1 is a structural beam clamp for 1/4 inch-20 threaded rod, supplied in packs of 100, so it attaches to the beam and the load hangs from the rod below it. The Steel City RC-4 SC is a conduit support beam clamp sized for 4 inch conduit and is sold each. If your design hangs trapeze or strut from rod, the FBC1 is the beam attachment; if the clamp has to hold the 4 inch conduit itself, use the RC-4.
5) How is the Steel City RC-4 clamp sold, individually or in a box?
It is sold each, so you order the exact count of hangers your run needs. That differs from some beam clamps that only ship in bulk cartons, like the Kindorf FBC1 which is packaged 100 to a pack.
6) Is the Steel City RC-4 beam clamp made in the USA for projects with domestic sourcing requirements?
Country of origin is the United States, which is what public and federally funded jobs with domestic material provisions typically need documented on electrical supports.
7) Does a beam clamp like the Steel City RC-4 need a hole drilled in the structural steel?
No drilling or welding. The RC clamp grips the beam flange mechanically, which is why these are used on existing structural steel where you are not permitted to penetrate the member. Confirm the clamp opening suits your flange thickness before you set the run.
8) For an outdoor or wash-down beam clamp, how does the Steel City RC-4 compare to the malleable iron alternatives?
The Steel City RC-4 is offered in malleable iron and in hot-dip galvanized steel as RC-4SCHDG, so the galvanized version is the one to specify for exterior runs, parking structures, or damp areas. The Appleton IS-500 beam clamp is malleable iron, and the Kindorf FBC1 is a structural beam clamp for 1/4 inch-20 threaded rod. If corrosion exposure drives the choice, the hot-dip galvanized RC-4 is the stated option among these.
