Minerallac BCUM37EG – Frequently Asked Questions

1) How much weight can this Minerallac beam clamp hang?
350 lbs maximum load per clamp. That covers typical conduit runs, HVAC duct and small piping suspended on 3/8 inch rod. Spread the run across enough clamps that no single point carries more than 350 lbs, and size your rod and fasteners to match.
2) Will this beam clamp fit my steel beam flange?
The Minerallac universal beam clamp grips flanges up to 5/8 inch thick. Anything thicker than 5/8 inch at the flange edge will not seat, so measure the flange lip and not the web before ordering. The clamp body itself is compact at 1-9/16 in high by 13/16 in wide, so it clears tight bar joist and beam bottoms.
3) What beam clamp should I use if my threaded rod is 1/4"-20 instead of 3/8"?
The Minerallac BCUM37EG is built around 3/8"-16 rod, so it will not take a 1/4" rod. For a 1/4"-20 hanger rod, the Thomas & Betts Kindorf FBC1 structural beam clamp is sized for that thread. Match the clamp to the rod you are actually hanging rather than adapting down.
4) Does the Minerallac BCUM37EG come with the set screw, or do I order it separately?
The set screw is part of the clamp, a 3/8" x 1-1/2 screw that bears against the flange. Snug it firmly but do not over tighten it; Minerallac calls that out specifically, and over torquing can damage the clamp or the thread. You still supply your own 3/8"-16 rod, nuts and whatever hanger or strap goes on the bottom end.
5) Is this beam clamp OK for a damp or unconditioned space like a parking garage or warehouse?
The BCUM37EG is steel with an electro-galvanized finish, which handles indoor and sheltered industrial environments such as warehouses, mechanical rooms and plant ceilings. Electro-galvanizing is a thin coating, so for direct weather exposure, wash-down areas or corrosive process environments you want a hot dip or stainless clamp instead.
6) Can I use one beam clamp to hang EMT conduit and trapeze supports from a bar joist?
Yes, that is the normal use. The clamp bites the beam or joist flange and gives you a 3/8"-16 rod drop, which is what most conduit hangers, trapeze channel and HVAC suspension hardware are sized for. Keep each drop under the 350 lb limit and keep the flange at the clamping point 5/8 inch thick or less.
7) Is the Steel City RC-2SC a direct swap for a Minerallac BCUM37EG?
They are both galvanized malleable iron beam clamps, so they occupy the same role, but they are not identical parts. The Minerallac BCUM37EG is rated for 350 lbs on 3/8"-16 rod with a 3/8" x 1-1/2" set screw. The Thomas & Betts RC-2SC is a Steel City 2-inch galvanized malleable iron beam clamp. Confirm the rod thread and flange you are clamping to before treating one as a drop-in for the other.
8) My beam flange is thicker than what the Minerallac clamp handles - what else works?
The BCUM37EG is a universal-style clamp with a compact 1-9/16" height and 13/16" width, sized for standard structural flanges. Where the flange is heavier than the jaw will open, the Thomas & Betts RC-2SC Steel City 2-inch malleable iron beam clamp is the wider-jaw alternative to check against your steel.
9) Does the finish differ between the Minerallac and the Thomas & Betts beam clamps?
The Minerallac BCUM37EG uses an electro-galvanized finish over malleable iron, intended for dry interior commercial and industrial spaces. The Steel City RC-2SC is likewise a galvanized malleable iron clamp. Neither is described for corrosive or exterior marine service, so specify accordingly for wet locations.
