Hey Walcrow ....................Their product does nothing more / different than several other vendors & mfg.'s have. Period. == I've used EagerBeaver, great product, they're the first that comes to mind.
The US Navy ET's calls them "terminal blocks" aka "term. blocks." a little different looking but the same end results.

Again, my question is: where have others installed them, that's safe & fairly easy to get to?

Too much ink over a simple question.
