I don't know anything about "consumer grade" punchdowns.
We use the same type the phone company uses. Since we
buy from industrial electronics suppliers, I wasn't even aware
of any "consumer grade" punchdown blocks. Where do you
find those?

I got mine for my home network from an industrial supplier. By the
way, the newer 110 blocks are usually rated for CAT5. The older 66
blocks mostly weren't. It's too hard to maintain the untwist specs
with the 66.

Home Depot has all this stuff now.
