Thomas & Betts 500-SC – Frequently Asked Questions

1) What is the difference between the Thomas & Betts 500-SC and a Kindorf FBC1 or Appleton IS-500 beam clamp?
All three clamp to a beam flange, but they differ in how the hanger attaches. The Appleton IS-500 is a screw-type clamp with a hexagonal head, tapped 1/4-20, and the Kindorf FBC1 is a structural beam clamp for 1/4 inch-20 threaded rod sold 100 to a pack. The 500-SC is the malleable iron, electro-plated option rated at a 450 lb static load limit and supports threaded rod, brindle rings, or electrical boxes. Pick by the rod size you are already running and the load you need.
2) Which beam clamp should I use if the steel is in a damp or corrosive area instead of the 500-SC?
Consider the Thomas & Betts RC-2SC Steel City beam clamp, which is galvanized malleable iron and sized for 2-inch beam flanges. The 500-SC is malleable iron with an electro-plated finish, which is the lighter-duty coating of the two, so for exposed or washdown locations the galvanized RC-2SC is the one to spec.
3) What is the closest equivalent to the Thomas & Betts 500-SC beam clamp from another brand?
The Appleton IS-500 is the nearest cross-brand match. Like the 500-SC, it is a malleable iron beam clamp; the IS-500 is a screw-type clamp with a hexagonal head and a 1/4-20 tapped hole for threaded rod. The 500-SC is malleable iron with an electro-plated finish and carries a 450 lb static load limit based on a safety factor of 3.
4) What can I hang off a 500-SC beam clamp?
It is built to support threaded rod, threaded brindle rings, and electrical boxes off a structural beam flange. Typical use is suspending conduit runs, light fixtures on rod, or box supports in commercial and industrial electrical work.
5) Is the Thomas & Betts 500-SC beam clamp RoHS compliant?
No. The 500-SC is listed as not RoHS compliant. If your project or agency spec requires RoHS documentation on hanger hardware, this clamp will not satisfy it.
6) Can I use the 500-SC beam clamp on a 2 inch beam flange?
For a stated 2 inch flange capacity, the Steel City RC-2SC is the clamp called out for 2-inch and comes in galvanized malleable iron. Match the clamp to the flange thickness and width on your steel before ordering either one.
7) I need a lighter-duty clamp just to hang 1/4-20 rod. Is there a simpler option than the 500-SC?
The Kindorf FBC1 structural beam clamp is built specifically for 1/4-20 threaded rod and is sold in packs of 100. It is the straightforward rod-hanger choice when you do not need the 450 lb static load capacity of the 500-SC, which also supports threaded brindle rings and electrical boxes.
8) Is the Steel City RC-2SC a drop-in substitute for the 500-SC?
Not automatically. The RC-2SC is specified for 2-inch beam flanges, so it is a flange-size-specific clamp rather than a general replacement. Check the flange width at your attachment point before swapping. Both are malleable iron, but the RC-2SC is galvanized while the 500-SC uses an electro-plated finish.
9) My spec calls for a 1/4-20 tapped beam clamp. Does the 500-SC meet that or do I need the Appleton IS-500?
The Appleton IS-500 is explicitly a screw-type malleable iron beam clamp with a 1/4-20 tapped hole, so it answers a spec written that way directly. The 500-SC is a malleable iron clamp rated for a 450 lb static load and designed to carry threaded rod, threaded brindle rings, and electrical boxes. If the drawing calls out the tap size, the IS-500 is the cleaner match on paper.
10) I buy beam clamps in bulk for a jobsite. How does ordering the 500-SC compare with the Kindorf FBC1?
The 500-SC is sold each and ordered in multiples of 50, with 50 to an outer package, and weighs 22 lbs per 100 pieces. The Kindorf FBC1 structural beam clamp is packaged as a pack of 100. If you are standardizing counts per floor or per panel run, those two break points are worth matching to your takeoff.
