There is a great chart hidden in the 8020 catalog that outlines the performance of the various fastner options.

I say hidden because it is not in the fastener section, it is in the extrusion section section of the catalog (go figure).

In my catalog it is on page 40 about 5 or 6 pages into section 1.

It lists how each fastener performs under the different kinds of loads (direct, cantilevered, tortional, etc)

It says the double anchors are best, but they are very hard to use because you heve to mill every piece (we did that last year - ugh).

This year we are using the corners mentioned in the previous post - much easier, though a lot of tapping. (These are on page 127 of my catalog in the joining plates section)
