B-LINE B321-1HDG – Frequently Asked Questions

1) What rod size does the B-Line B321-1HDG beam clamp take?
It takes 3/8-16 threaded rod, and the setscrew that locks it to the beam flange is also 3/8-16. Since it's tapped rather than supplied with rod, you order the rod, nuts and washers separately to suit your drop length.
2) Is this beam clamp UL listed for electrical support?
Yes, the B-Line B321-1HDG carries a cULus Listing, which covers it in both the US and Canada. That matters if you're supporting conduit or cable tray on a job where the inspector wants listed support hardware rather than generic rigging parts.
3) Can I use a hot-dipped galvanized beam clamp outdoors or in a parking garage?
The HDG suffix on the B321-1HDG means hot-dipped galvanized steel, which is the finish specified for damp, washdown and exterior locations such as parking structures, loading docks and unconditioned warehouses. For dry interior work a plain or electro-galvanized clamp is the usual choice.
4) How much room does the B321 clamp need around the beam flange?
The clamp body measures 3.5625 in high, 3.25 in deep and .625 in wide, so allow for that envelope where the flange sits close to deck, duct or another trade's run. Each piece weighs 1.87 lb, which is worth knowing when you're counting a pallet of them into a high-rise riser.
5) Do I need to weld or drill the beam to hang conduit from it?
No. A beam clamp like the B321 grips the flange and is locked with its own setscrew, so nothing gets drilled, welded or coped. That's the reason it's the standard way to pick up a hanger rod on structural steel where the building owner or the structural engineer will not permit holes in the member.
6) Is anything else needed to finish the install besides the beam clamp?
The setscrew ships with the clamp. Everything below it is separate: the 3/8-16 threaded rod cut to your drop, the nuts and washers at the rod, and whatever hanger, strut or trapeze channel actually carries the conduit or pipe. Order those on the same line so the crew isn't short on the lift.
7) Can I standardize a facility on one beam clamp part number?
The B321-1HDG is a single-model item, so there's one part number to stock and one rod size to keep on the shelf. For a maintenance crib it means the same 3/8-16 rod, nuts and washers serve every clamp, and the galvanized finish lets one bin cover both interior and exposed locations.
