Steel City RC 1/2 Beam Clamp

Same beam clamp, different finish. RC 1/2 is the standard finish version and RC-1/2HDG is hot-dip galvanized, which is the one to specify for outdoor, damp, or corrosive locations such as parking structures, tunnels, and exterior runs. Indoor dry areas are where the standard finish normally goes.

The Steel City RC 1/2 beam clamp is a 1/2 size clamp offered in a standard finish and a hot-dip galvanized version under part number RC-1/2HDG. If the hanger run is 1/4-20 threaded rod, the Appleton IS-500 malleable iron beam clamp is a screw-type clamp with a hexagonal head and a 1/4-20 tapped hole, and the Kindorf FBC1 is a structural beam clamp built for 1/4-20 threaded rod. Match the clamp tapping to the rod the conduit or strut hangers are already using so you are not adapting threads at every drop.

No. The RC 1/2 is a fixed, non-rotatable beam clamp. If your drop needs the hanger to swivel or self-align to an angled or sloped beam flange, this is not the part for that condition.

The Steel City RC 1/2 beam clamp ships in an outer quantity of 50, so a full carton covers 50 hanger points. The Kindorf FBC1 structural beam clamp is packaged 100 to a pack, which suits a job where you are setting drops across a whole floor in one pass. Both are beam clamps for structural steel; the difference to plan around is the carton count and the rod size they are tapped for.

Specify the Steel City RC 1/2 in the hot-dip galvanized version, part number RC-1/2HDG. Hot-dip galvanizing is the finish to call out where the clamp sees weather, condensation, or washdown. The comparable Appleton IS-500 is described as a malleable iron clamp and the Kindorf FBC1 as a structural beam clamp, without a galvanized finish called out, so for exterior steel the galvanized RC-1/2HDG is the straightforward pick.

The RC 1/2 beam clamp ships in an outer quantity of 50, so pricing and packaging are built around that carton. Useful if you are laying out a full floor of conduit or hanger drops and want to order by the box rather than the piece.

Beam clamps are the attachment point when you need to hang conduit, strut, cable tray, or fixture drops from structural steel without welding or drilling the beam. The RC 1/2 is an electrical department beam clamp in the hangers, supports and fasteners family, so it is the piece between the building steel and your rod or hanger. Pick the hot-dip galvanized RC-1/2HDG where the steel is exposed to weather.
