... I set the dial to 10 and measured the adaptor output - on the scale you circled the needle stopped about 8.5 volts. If that's the right line to read the voltage and its accurate, then the adaptors from Menards are indeed putting out more voltage then they specify...

If you are reading the output with an open circuit - no load - then that is about right what you are reading. For an accurate measure, the load has to be close to the rated output(2 amps is the specification you give above in your OP). Any (expected) load will get it closer to 4.5 volts quite quickly.
