Carl,I have used fablok fasteners and "never drop" or toggle anchors for very
similar applications and liked them. I just don't trust Tek Screws for
attaching racking systems.
Never drop:http://www.mcmaster.com/#catalog/115/3266/=46tlns
Fablok:http://www.aboveboardelectronics.com/camcar/fablock.html
Both require additional work to install, but are worth knowing the connection
is solid (no spinnners).
Cheers,Tommy Jacoby
