Eaton B-Line series cable support fasteners, Conduit and cable, Flange, 1" Height, 1" Length, 1" Width, 0.014lbs, Flexible conduit fastener, .16" Max

The B-Line BX9 flange-mount fastener grips cable or flexible conduit from .42 inch up to .7 inch outside diameter. Measure the OD of what you are running, not the trade size, since jacketed low voltage cable and flex vary from the nominal number. Anything under .42 inch will sit loose in the clip and anything over .7 inch will not seat.

It is a flange-type fastener, so it clips onto the edge of a structural flange rather than being screwed into the substrate. The maximum mounting thickness it will accept is 0.16 inch, which covers thin flanges like beam edges, bar joist angles and light gauge steel. If the flange you are clipping to is thicker than 0.16 inch, this one will not go on and you need a different support method.

Yes, the BX9 cable and conduit support fastener is UL Listed. That matters on inspected commercial and institutional jobs where the support hardware on a low voltage or flex run has to be a listed product, not a field-made strap.

The BX9 is zinc plated steel. Zinc plating is a general purpose indoor finish - fine for dry interior runs above ceilings, in mechanical rooms and along steel framing. For exterior or consistently wet locations, a plated carbon steel clip is not the right pick.

It is a compact piece, 1 inch in height, length and width, and it weighs .014 lb. That 1 inch envelope is worth checking when you are stacking multiple runs along the same flange or working in a tight ceiling cavity, and the weight is negligible for load on the structure.

The manufacturer part number is BX9, from the Eaton B-Line series of cable support fasteners. That is the number to quote when ordering or standardizing a fastener across a facility so every run uses the same clip.
