How does the attachment strength of an Ejot Solar Fastener compare to that of a Unirac standoff?

The Ejot Solar Fastener uses only one hanger bolt, whereas the Unirac Standoff uses two lag bolts. Which attachment is stronger? The application is a trapezoidal metal roof with a wood substructure.

Emmett,The fasteners have about the same pull-out strength, but the stand-off is much more resistant to lateral loads. The benefit of the Ejot is that it is made to waterproof the attachment point without additional hardware.

Thanks for the information. I think, I'll prefer the fastener.
