So I've stumbled across globalindustrial.com and other, similar "commercial-centric" websites that seem to sell everything and anything and it got me thinking...what sort of industrial/commercial equipment can you buy online (or wherever, like at auction) that one could use for the DIY lifestyle (and/or mischief). e.g. telephone company "butt-sets" that you can use with ye olde phone cables.
You could buy some real nice glass cleaner or some fiberglass sealer.
Butt sets aren't really that exciting. You can buy one at home depot and everybody has got test hacks on the side of their house these days, you hardly need the test clips on the butt set.
Mostly they're useful because you can verify current and polarity with one or talk to your buddy on the other end of the line while you're splicing.
Industrial surplus sites are where its at. High quality products at rock bottom prices.
I recommend
Meci.com
There are plenty of others though so just browse search engines a little.
Meci interface sucks but their electrical section is a gold mine for numerous projects
