B-Line Eaton series strut pipe clamps and accessories, .0994" height, 5.683" length, 1.25" width, 800 lbs, Steel, O.D pipe conduit clamp, Electro-plat

It is an O.D. pipe conduit clamp, so it is selected against the actual outside diameter of what you are strapping, not a nominal trade size. Match the measured O.D. of the conduit or tube before ordering, since nominal sizing across steel pipe, copper tube, and EMT gives three different outside diameters for the same stated size.

Yes. The B2048PAZN is the clamp only. You supply the strut channel it mounts to, plus the channel nut and bolt that fasten it, and whatever anchors or beam attachments carry the strut back to the structure. Order those to match the strut series you are running.

The clamp measures .0994 in height, 5.683 in length/depth, and 1.25 in width, and weighs .43 lb. The 1.25 in width is the figure that matters when you are spacing multiple clamps along a single length of strut, since it sets how tight you can gang parallel conduit runs.

It is electro-plated zinc steel. That plating is a dry-interior and sheltered-location finish; for exposed exterior, washdown, or corrosive environments you want a hot-dip galvanized or stainless clamp instead, because electroplate is a thin coating and will rust out first at the cut edges and the bolt hole.

Order it as Eaton B-Line B2048PAZN. The PAZN suffix denotes the electro-plated zinc steel finish, so if a submittal calls for a different finish on the same clamp body, the suffix is the part of the number that changes.

They solve different problems. A one-hole strap fastens conduit straight to a surface. A strut clamp like the B2048PAZN rides on channel, which is what you want for racked or trapeze runs, for multiple parallel conduits off one support, or where the conduit is standing off a wall or hung from a ceiling. On a single run tight to drywall or block, a strap is simpler and cheaper.
