Actually the vertical arms of the 24x27 TorkLift Lock and Load Maximum Security Cargo Tray # TLA7752 are not held to the carrier with wing nuts. They actually fit through a slot and then rotate 90 degrees which holds them in place. Once you assemble the arms around the generator and secure them there wouldn't be a way to easily disconnect the arms and remove the generator. I am not sure which video you watched but I attached a link to this page that I think might show this more clearly. view full answer...
