They are used a lot in indusial installations and all you have to do is cut some DIN rail to size to fit with in the case, once the rail is cut the blocks clip on and can be bridged together.

Here’s a link to DIN rail stuff so you can get an idea what I’m talking about, this stuff can be found at a electrical wholesaler too.

Earth examples terminal block. (this one has 4 connection points, it's width is 6.2mm so... 6.2 x 5 = 31mm width in total)

Don’t forget the Bridge, Some clip-in and some screw-in (it depends on the manufacture of the terminal block)

On a saftey note: DON'T forget to earth the 19"rack case too, you don't wont to kill anyone with mains power if there is a fault.
I appreciate it! These terminal blocks are DIN/direct mount. I just opted for direct mount because I didn't want to spend 70 dollars just to cut off 18 inches of rail. I'm still debating if I'm going to nutplate all the mounting holes in the chassis. Would be cleaner, but I am not much of a riveter.

That’s fine… we all have preferences how to do things, But I have no idea where you have got your unit costing from?

http://www.rs-components.com/index.html is just one of many world wide supplers
---------------------------------------------------------------------------------------------------------------
-Standard Top hap DIN rail at 0.5 meters long unit price is $4.79 http://australia.rs-online.com/web/p/din-rails/7424129/
-4 way earth block unit price is $3.20 ( need to buy a pack of 5, $3.20 x 5 = $16) http://australia.rs-online.com/web/p/ea ... s/6247104/
-End stops to make it look nice unit price is $2.65 ( $2.65 X 2 = $5.30) http://australia.rs-online.com/web/p/di ... s/7427128/

Total cost with end stops is $26.79 (this is in Australian dollars) that is $43.91 less the $70.

Anyhow looking at things a little closer you do not even need 18 grounds as you can just common the grounds along the back of your lights and switches in a daisy-chain fashion
