B-LINE B321-5ZN – Frequently Asked Questions

1) What size threaded rod does the B-Line B321-5ZN beam clamp take?
The B321-5ZN beam clamp is tapped for 3/4"-10 threaded rod, and the setscrew that locks it to the beam flange is also 3/4"-10. If your hanger rod is 1/2"-13 or 3/8"-16, this is the wrong size clamp, pick the matching rod size in the series instead.
2) Is the B-Line B321-5ZN beam clamp UL listed for electrical support work?
It is cULus Listed, which is what most inspectors and institutional specs want to see on a support used for conduit, cable tray, or raceway hangers in commercial and industrial buildings. It is a steel clamp catalogued for electrical support use.
3) Do I need to buy a setscrew separately with this beam clamp?
No. The setscrew ships with the clamp, in the 3/4"-10 size. What you still have to supply is the 3/4"-10 threaded rod, the rod nut, and whatever trapeze channel or hanger hardware sits below it, none of that is part of the clamp.
4) Is the zinc finish on the B321-5ZN beam clamp okay for outdoor or damp locations?
The B321-5ZN is steel with an electro-plated zinc finish. That is a standard indoor and protected-area finish, fine for mechanical rooms, plenums, and covered structures. For direct weather exposure, washdown areas, or corrosive environments, specify a hot dip galvanized or stainless version of the beam clamp instead.
5) How much room does the B-Line B321 beam clamp need around the beam flange?
Plan on 3.71875 in height, 3.25 in length/depth, and .625 in width for the clamp body. That matters when you are hanging tight to a deck, beside a duct, or where several trapezes land on the same beam. Each clamp weighs 2.38 lb, which adds up on a long run of hangers.
6) What is the exact part number for this 3/4 inch B-Line beam clamp?
Order it as Eaton B-Line B321-5ZN. The 5 designates the 3/4"-10 rod and setscrew size and ZN the electro-plated zinc finish, so if a submittal calls out a different suffix you are looking at a different rod size or finish in the same B321 family.
