Yeah, here's the links to what I was referring to.
This one
Musician's Gear Double Microphone Attachment | Guitar Center will take two of those standard mic clips.
And this one
Sabra Som ST4 Four Mic Bar | Guitar Center will take four of those clips.
There's cheaper 4 place bars than that one above, they are similar to the two place one. And you can see the price difference on that Sabra Som, is a bit higher because the anchors are more complex than the two place one. They can slide- side to side, along the bar. Whereas the two place anchors are fixed to the bar.
If you want to go check them out before you plunk down some ducats, just swing by your local Guitar Center, to check them out. They usually have quite a bit of gear set up in-store.
So you can see first hand before ordering from them or elsewhere. Guitar Center 1011 W Avenue P, Palmdale, CA 93551 that is probably the closest one to ya' Bob.
They will usually have quite a few different mic stands on display as well, tripod and solid base types. For extra grip on the clips, we sometimes just used some small diameter rubber tubing and slit it lengthwise, then slid it over the knife edges of the clips to keep the mics from slipping out. If that didn't do the trick- we broke out the Duct tape!
Usually we only had to do that for mics that were pointing downward at sharp angles
