B-Line Eaton series strut pipe clamps and accessories, .12" height, 7.297" length, 1.25" width, 1000 lbs, Steel, Includes combination recess hex head

The mounting screw is included. Each B2018PAZN ships with a combination recess hex head machine screw, so you are not buying fasteners separately for the clamp itself. What is not included is the strut channel and the channel nut or spring nut that the screw threads into, plus whatever anchors the channel to the structure. Order those with the job.

It is steel with an electro-plated zinc finish. That plating is a standard indoor and dry-location protection, fine for mechanical rooms, ceilings, plenums and interior industrial runs. For exterior exposure, wash-down areas, coastal air or corrosive process environments, step up to a hot-dip galvanized or stainless strut clamp instead; electro-zinc will rust out in those conditions.

It measures .12 x 7.297 x 1.25 inches (height, length, width as published) and weighs .7 lb. The 1.25 inch width is the dimension that matters for layout, since it sets how tightly you can space clamps along a single run of strut when you are ganging multiple conduits on one channel.

Order it as Eaton B-Line B2018PAZN. That single manufacturer part number is the whole item, so a re-order or an add-on to an existing run matches what is already installed with no options to specify. Confirm the clamp on the existing run is the same B2018PAZN before assuming identical fit; B-Line's strut clamp line covers many pipe sizes under different numbers.
