Minerallac 500 – Frequently Asked Questions

1) What size beam flange will the Minerallac 500 beam clamp fit?
The Minerallac 500 set screw beam clamp grips flanges up to 1/2 inch thick. If the beam flange on your job is thicker than that, this clamp won't seat on it and you need a larger-capacity clamp. The clamp body itself is small, 1.42 x 0.70 x 1.25 inches, so it works in tight spots alongside other trades' hangers.
2) Can I hang 3/8 inch threaded rod from the Minerallac 500 beam clamp?
Yes. The 500 has pass holes sized for both 1/4 inch and 3/8 inch threaded rod, so it covers the two rod sizes most electrical and HVAC hangers use. Note the rod passes through, so you'll need nuts top and bottom to lock it off; threaded rod and nuts are not included with the clamps.
3) How much weight can a single Minerallac 500 beam clamp carry?
Rated at 100 lb maximum load per clamp. That covers typical conduit runs, small cable tray, light fixtures and strut drops. For heavier mechanical equipment or large multi-conduit racks you want a malleable iron clamp instead, such as the Appleton IS-500 or the Thomas & Betts RC-2SC Steel City clamp, rather than spring steel.
4) What is the closest equivalent to the Minerallac 500 beam clamp if I need a malleable iron body instead of spring steel?
The Minerallac 500 is a spring steel clamp with a zinc phosphate finish, fitting flanges up to 1/2 inch. If you want a cast body, the Appleton IS-500 is a malleable iron beam clamp with a screw-type hexagonal head and a 1/4-20 tapped hole, and the Thomas & Betts RC-2SC Steel City clamp is galvanized malleable iron sized for a 2 inch flange. Malleable iron clamps are heavier and bolt down with a hex head screw; the spring steel 500 relies on its set screw and spring body against the flange.
5) My beam flange is wider than 1/2 inch - what should I use instead of the Minerallac 500?
The Minerallac 500 is built for flanges up to 1/2 inch, so a thicker flange is outside its range. The Thomas & Betts RC-2SC Steel City beam clamp is a 2 inch galvanized malleable iron clamp and covers the heavier flange thicknesses that the 500 cannot reach. Confirm the actual flange thickness at the point of attachment before ordering either one.
6) I am only hanging 1/4-20 threaded rod. Is there a simpler clamp than the Minerallac 500?
Yes. The Kindorf FBC1 structural beam clamp is made specifically for 1/4 inch-20 threaded rod and also ships 100 to a pack. The Minerallac 500 is the broader choice because it has pass holes for both 1/4 inch and 3/8 inch rod plus 1/4-20 and #10-24 thread impressions, so pick the 500 if you want one clamp that covers both rod sizes on the same job and the FBC1 if every drop on the job is 1/4-20.
7) Can I screw a fixture or box directly to the beam clamp instead of using rod?
Yes, that's what the thread impressions are for. The 500 carries 1/4"-20 threads on the bottom and the back of the clamp, plus #10-24 on the back, and has two fastening holes. So you can hang rod off the bottom, or fasten a box, strap or small fixture straight to the back of the clamp without a rod drop at all.
8) Is a spring steel beam clamp or a malleable iron beam clamp the right choice?
Spring steel clamps like the Minerallac 500 snap onto the flange and tighten with a set screw, which makes them fast to install in volume and good for light loads up to the clamp's 100 lb rating. Malleable iron screw-type clamps, like the Appleton IS-500 with its hexagonal head and 1/4-20 tapped hole, are the heavier-duty route when load or vibration is the concern. For 1/4"-20 rod work in bulk, the Kindorf FBC1 structural beam clamp is another 100-pack option.
9) Will a zinc phosphate beam clamp hold up outdoors or in a damp area?
Zinc phosphate is a black protective coating that improves corrosion resistance over bare steel, and it's well suited to interior commercial and industrial work. For wet or exterior exposure, a galvanized clamp is the better call; the Thomas & Betts RC-2SC Steel City clamp is galvanized malleable iron.
10) Are Minerallac beam clamps made in the USA for a Buy American spec?
The Minerallac 500 beam clamp is manufactured in the United States, which is the detail that matters on federal, state and institutional jobs carrying domestic-sourcing language. Country of origin is United States as supplied.
11) Does the Appleton IS-500 accept 3/8 inch threaded rod like the Minerallac 500?
No. The Appleton IS-500 is a screw-type malleable iron clamp tapped 1/4-20, so it is a 1/4 inch rod device. The Minerallac 500 carries pass holes for both 1/4 inch and 3/8 inch threaded rod, so if any of your drops step up to 3/8 inch rod the 500 is the one that takes them without a second part number.
12) For an outdoor or damp structural location, how does the Minerallac 500 finish compare to the alternatives?
The Minerallac 500 uses a black zinc phosphate finish over spring steel. If you want a galvanized coating on a cast body for a wet or exterior steel location, the Thomas & Betts RC-2SC Steel City beam clamp is galvanized malleable iron. Match the clamp coating to the rest of the support assembly so you are not mixing coatings at the connection.
13) How many Minerallac 500 beam clamps come in a box?
They ship 100 clamps to the pack, which is the practical count for a crew running conduit or fixture drops across a floor. Only the model 500 clamp is sold on it, so there's no size or finish decision to make at order time.
