strange strut clamp

[gregoryfast]

I was inspecting a job today. The contractor was running 1/2" rigid conduit. Going into the panel above and below he installed a piece of unistrut. To clamp the conduits, he used some clamps I have never seen before. They fit into the strut with the same ears as normal strut clamps. It appears to be one solid piece with earss on each end. In the center of it was a 1/4"- 20 bolt that screws into the conduit. The contractor said he got them from B-line. He didn't have a box to look at. I couldn't find them in the B-line catalog.
Has anyone else seen these clamps?
Are they UL listed for clamping rigid conduit?
