The BCH12-C2 beam clamp grips flanges up to 1/2 inch thick. It bites onto the edge of an existing beam or bar joist flange, so nothing needs to be drilled or welded. If the flange on your steel is thicker than 1/2 inch, this clamp will not seat and you need a larger-opening clamp.

Yes. The hook rotates a full 360 degrees on the fastener, so you can set the clamp on the flange first and then swing the saddle to line up with the cable path, whether the run is parallel to the beam, crossing it, or dropping off at an angle. That matters on retrofits where the beam orientation does not match the tray route.

The BCH12-C2 is UL/CUL listed and is built specifically as a datacomm and low voltage cable support fastener. Inspectors on commercial data cabling jobs typically want independent support for communications cable rather than cable laid on ceiling grid or pipe, and a listed J-hook on a beam clamp is the standard way to provide it.

It is steel with a pre-galvanized finish, which covers dry interior and normally protected indoor spaces. Pre-galv is a thin mill coating, not hot-dip, so for washdown areas, exterior runs, or corrosive environments choose a hot-dip galvanized or stainless version rather than this one.

No separate anchors, screws, or beam drilling. The clamp assembly mounts directly to the beam flange and the J-hook comes attached, so it is a one-piece install per support point. Each part ships as a single hook, so order one per support location along the run.

The assembly measures 5.465 in height, 1.02 in length/depth and .86 in width, and it weighs about .2 lb. That footprint matters in a tight plenum: budget roughly five and a half inches of vertical space from the beam flange for the clamp and hook before cable is loaded into it.

A beam clamp hook like the BCH12-C2 is the faster choice wherever there is exposed structural steel to grab, since it needs no drilling, no anchors, and no rod. Threaded rod hangers make sense when the support point is a concrete deck, when the cable has to drop well below the structure, or when the bundle weight exceeds the 30 lb rating of a single hook.
