Well, Rigblasters are sold for ham radio use, though to be honest they can be used for any 12vdc distribution up to 30 amp loads

That's the folks who make it... You can order direct. You will want the crimping tool, it's not cheap, but it gives the best crimp I've ever seen when properly used
Here is another manafacturer of a very simular product, Saratoga Power Panels... they use the same connectors

I find these to be very useful as 12 volt power strips. Very easy to connect/disconnect equipment and to move it from vehicle to vechicle so long as it's equiped with a strip
