Steel City Beam Clamp Conduit Hanger Malleable Iron

Three sizes of the Steel City PC beam clamp are offered: 1 inch (PC 1), 3 inch (PC 3), and 4 inch (PC 4). The size refers to the conduit the clamp hangs, so match it to the trade size of the run you are supporting, not to the beam flange.

It is built to CSA 12798, which is the certification an inspector on a Canadian project will look for on a conduit support clamp. The clamps are made in the United States.

The PC style clamp attaches to the beam flange and carries the conduit itself, so it is the one-piece solution where the raceway runs tight to the steel. If you need to drop the conduit below the beam, use a tapped or rod-type beam clamp instead with threaded rod, such as the Appleton IS-500 screw-type clamp tapped 1/4-20 or the Kindorf FBC1 structural beam clamp for 1/4 inch-20 rod.

The Appleton IS-500 is the closest like-for-like option: it is also a malleable iron beam clamp, using a screw-type hexagonal head and a 1/4-20 tapped hole for rod or hanger attachment. The Steel City PC beam clamp is likewise malleable iron and comes in 1 inch, 3 inch and 4 inch sizes, sold each. Both are used to hang conduit from structural steel without drilling or welding the beam.

For a 1/4-20 threaded rod drop, the Kindorf FBC1 structural beam clamp is specified for 1/4 inch-20 threaded rod, and the Appleton IS-500 is 1/4-20 tapped. The Steel City PC beam clamp is a malleable iron conduit beam clamp offered in 1 inch, 3 inch and 4 inch sizes, each sized to the conduit it carries rather than described by a rod thread, so confirm the attachment style you need before ordering.

Malleable iron. It is a cast, load-bearing clamp rather than a stamped spring steel one, which is why it is used for conduit support on structural steel in mechanical rooms, parking structures, and plant ceilings. For wet or corrosive exposure, confirm the plating finish on the part you order.

The Kindorf FBC1 structural beam clamp is supplied in a pack of 100, which suits a repetitive rough-in where the same drop repeats across a floor. The Steel City PC beam clamp is sold each, which fits smaller counts or mixed sizes, since it is offered in 1 inch, 3 inch and 4 inch.

The Steel City PC beam clamp is listed with country of origin United States, is malleable iron, and carries CSA 12798. Among the comparable malleable iron screw-type clamps, the Appleton IS-500 is the nearest alternate in construction, with a hexagonal screw head and 1/4-20 tapped hole.

These Steel City PC clamps sell each, so you can take the exact count a job needs. If you are stocking a truck or a repeat install crew, the Kindorf FBC1 structural beam clamp comes in packs of 100.
