B-Line Eaton series strut pipe clamps and accessories, .0994" height, 4.877" length, 1.25" width, 800 lbs, Steel, Include combination recess hex head

It is an O.D. pipe conduit clamp, meaning it is sized to the actual outside diameter of what you are strapping rather than a nominal pipe size. Measure the tube or conduit across its outside face before ordering; nominal trade sizes and true O.D. do not match on most pipe.

The fastener is included. Each B2043PAZN ships with a combination recess hex head machine screw, so you are not sourcing hardware separately for the clamp itself. You still supply the strut channel and the channel nut or spring nut that anchors it.

It is steel with an electro-plated zinc finish. That plating suits dry indoor and protected mechanical rooms. For sustained outdoor exposure, wash-down, or coastal air, step up to a hot dip galvanized or stainless strut clamp instead, since plated zinc is a thin sacrificial coating and will rust out first at the cut edges and screw threads.

A strut clamp like the B2043PAZN is what you use when the conduit is running on unistrut rather than fastened flat to a wall or deck. It bolts into the channel and holds the conduit off the structure, which is how multi-run racks are built. One-hole and two-hole straps are the cheaper choice only when you are fixing a single run directly to a surface with no channel behind it.

Published figures are .0994 in height, 4.877 in length/depth, and 1.25 in width, at .38 lb each. The 1.25 in width is the number that matters most on a crowded strut run, since it sets how tightly you can space adjacent clamps on the same channel.
