B-LINE B321-4HDG – Frequently Asked Questions
1) How much weight can a B-Line B321 beam clamp hold?
Rated at 1800 lb, with a safety factor of 5 built into that rating. That covers most conduit runs, trapeze supports, and pipe hangers dropped from structural steel, but the 5/8"-11 rod you hang from it and the structure itself have to carry the load too.
2) Is the B-Line B321 beam clamp UL listed for electrical support?
It is cULus Listed, so it is accepted for both US and Canadian installations where an inspector wants a listed support component for conduit and cable tray hung off structural steel.
3) Can this beam clamp be used outdoors or in a parking garage?
Yes. The B321-4HDG is steel with a hot-dipped galvanized finish, which is the finish specified for exposed exterior steel, wash-down areas, and unheated structures like decks and garages. For dry indoor conditioned space a plain electro-galvanized clamp would do the same job.
4) Does the beam clamp come with the setscrew, or do I have to order it separately?
The setscrew ships with the clamp, so no separate hardware to buy. What is not included is the threaded rod itself, plus whatever nuts and washers you need at the rod end, order 5/8"-11 rod to match the tapped hole.
5) Is a beam clamp the right choice, or should I drill and anchor into the structure?
A beam clamp like the B321 is the usual pick when you have exposed structural steel, it grips the flange with a setscrew and needs no drilling, welding, or hot work permit, and it can be moved if the layout changes. Concrete deck or no exposed steel is where you go to a drilled anchor instead. This one drops a 5/8"-11 rod and carries up to 1800 lb.
