I got very similar for a lot less money from Grizzly. I can do chin-ups
on
the 12" brackets. IIRC earlier this year I bought 4-4" standards, 12-12"
brackets, and 4-18" brackets for about $110.00 delivered.

Don't know about cost or quality, but I've seen similar brackets available
at Home Depot. As a matter of fact, the HD I go to was using them for some
of their racks.
