Steel City RC-3/4HDG – Frequently Asked Questions
1) What's the difference between the Steel City RC 3/4 beam clamp and the RC-3/4HDG version?
The difference is the finish. The RC 3/4 is the standard-finish clamp; the RC-3/4HDG is hot-dip galvanized, which is the one to use outdoors, in wash-down areas, or anywhere else corrosion is a concern. Mechanically they are the same 3/4 beam clamp, so pick on environment and keep the part number consistent across a job for matching appearance.
2) What beam clamp works with 1/4-20 threaded rod instead of the Steel City RC 3/4?
For 1/4-20 rod, look at the Kindorf FBC1 structural beam clamp, which is built for 1/4"-20 threaded rod and supplied in packs of 100, or the Appleton IS-500 malleable iron beam clamp, a screw-type clamp with a hexagonal head and a 1/4-20 tapped hole. The Steel City RC 3/4 beam clamp is the 3/4 size and comes in a standard finish as RC 3/4 and a hot-dip galvanized version as RC-3/4HDG.
3) Does the Steel City RC 3/4 beam clamp swivel or rotate once installed?
No. The RC 3/4 is a non-rotatable clamp, so the hanger point is fixed in the orientation you set when you tighten it on the flange. If your run needs the drop to pivot or align off-axis after installation, this is not the clamp for that.
4) Is a hot-dip galvanized beam clamp necessary for outdoor or parking garage conduit supports?
For exposed exterior steel, parking structures, or wash-down interiors, go with the galvanized version, RC-3/4HDG. Hot-dip galvanizing is the coating specified for those conditions. Reserve the standard-finish RC 3/4 for dry, conditioned interior spaces.
5) For a job needing 100 beam clamps in one carton, what is an alternative to the Steel City RC 3/4?
The Kindorf FBC1 structural beam clamp is supplied as a pack of 100, while the Steel City RC 3/4 beam clamp ships in an outer quantity of 50. The FBC1 is sized for 1/4"-20 threaded rod, so verify your rod diameter matches before ordering it in place of the RC 3/4.
6) What is a beam clamp like the Steel City RC 3/4 used for on an electrical job?
A beam clamp attaches a hanger, rod, or support to a structural steel flange without drilling or welding the beam. On electrical work it is how conduit runs, strut, and fixture drops get picked up off the building steel. The RC 3/4 is the 3/4 size in Steel City's RC line and is available either standard or hot-dip galvanized.
