Those locking dogs, the lifting cables or rotary rods, that's where the focus needs to be placed to determine quality and safety.
Point taken, I guess what I meant was open extrusion...Mine is a 1/8 inch thick closed hollow pole with laser cut holes for the dogs to go into. The fact the poles(uprights) are open and being compressed down will try and make the opening spread more open. There is lots of info on their site if anyone is interested. At the time, I was very interested in safety and I am just trying to share what I had learned...as i have said previously, not trying to down anyone's stuff here!
