Connect a RigRunner your power supply and Power Pole connectors to your various rigs.  Here's one example: https://powerwerx.com/west-mountain-radio-rigrunner-4012

If this is the one with holes in the back with set screws to attach banana plugs to, I bought some bolts that were several inches long, cut the heads off of the screws, put them in the holes, and then tightened the set screws so they would stay in the holes.  I put ring terminals on each power cord and put them on the bolts, with a nut tightening each ring terminal down on the bolt.

The above works fine. Make sure the radios and power supply all have fuse connectors in the plus leads.

Or, you could go to Lowes and by some of these grounding bars, and use one for red wires and one for black, with one wire (sized right with fusing) to the bar itself.

Just mount the bars to a wood block, spaced a couple of inches apart.

This is about the simplest way.   Unfortunately, that  type of connector which is used on some of the switching power supplies like Samlex and Astron do not lend themselves to connecting to multiple power leads.

I agree with KF4HR on the RIGrunner. I've used the model 4008 for many years and for me it's the slickest way to connect--and disconnect when necessary--accessories to any power supply. Plus, they will each have their own fuse.

Use the same thing all industries and technologies use. Use a Battery Fuse Distribution Block. You use a feeder cable from PS like a #6 AWG to the Fuse Distribution block. There are many available. I prefer to use listed products made for Marine Environments. Lots of products out there to do this as already mentioned. Something like this. In fact I have a couple I can let go of.

I use the MFJ-1129 power strip with Anderson power pole connectors and automotive type fuses. My station is solar with very high current distribution and even though the master is a 50 amp. main off switch not having everything fused or through circuit breakers is asking for an oppsie to turn into a big flash fire.

For $139 and change the setup is very nice.
