B-LINE B2121ZN – Frequently Asked Questions
1) What size hardware does the B-Line B2121ZN pipe clamp take?
The B2121ZN takes 3/8"-16 bolt/pin hardware, and it comes with a combination recess hex head machine screw. So you can set the clamp without sourcing the screw separately, but any rod, strut nut, or anchor you tie it into needs to be 3/8"-16 as well.
2) Is the B2121ZN sized by pipe O.D. or by nominal trade size?
It is an O.D. pipe conduit clamp, so it is selected off the actual outside diameter of the pipe or conduit, not the nominal trade size. Measure the O.D. of the run before ordering, since copper, steel pipe, EMT, and rigid conduit of the same nominal call-out all have different outside diameters.
3) What are the dimensions and weight of the B-Line B2121ZN clamp?
The B2121ZN measures 11.081 in length/depth, 1.25 in width, and .12 in height, and weighs 1.14 lb. The .12 in figure is the strap stock thickness, so it fits tight against pipe without eating much clearance behind the run.
4) Does the B-Line B2121ZN come with a mounting bolt or rod?
What ships with it is the combination recess hex head machine screw that closes the clamp. Threaded rod, strut, beam clamps, or concrete anchors are all separate and ordered to suit the support method on your job.
5) Is the B-Line B2121ZN clamp steel, and will it hold up in a damp mechanical room?
It is a steel clamp. Steel with a plated finish is normal for indoor and covered mechanical spaces; for corrosive or continuously wet exterior service, spec a stainless or hot dip galvanized clamp instead.
6) Do I order the B-Line B2121ZN by any other part number?
One part number covers it: B-Line B2121ZN, manufacturer part number B2121ZN. There are no size or finish options to select under it, so the model number alone specifies the item.
