That is a beefy solution. But I'm just looking to hold a stack of
maybe 10" high x 8" wide hardwoods -or- 10" high x 10" wide 2x
materials. Even their photo shows the rack 80% unused. For that,
the cheap brackets are plenty strong. That's my point -- I only ever
want to put at-most 10" of material on them -- because I don't want to
sort through 20 boards. With that in mind, each bracket only needs
to support 50# or so.

To load a 100# bracket with 8e# is an accident waiting to happen.

83 # is the number you provided.
oak 50#/cuft
50 x 8' x 12" x 10" / 4 supports = 83 # / support

50# would be safer.

So would 20 be even safer...

The 80lb is assuming a very high density for domestic hardwoods and also
a 100% loading w/ a 100% packing factor. It just ain't agonna' happen in
reality.

Folks getting awfully carried away here--the worst that happens anyway
is he spills a few boards on the floor he gets to pick up and put away
again.

Or a 30# child pulls up on the boards and they come falling down on him
or her.
