Thanks, i have more tricks up my sleeve................stay tuned.
Yes, they are very sturdy and can assist on lifting you up. I didn't use the hardware that was provided, tho. The nutserts that came with the kit easily stripped on me so, I used some thick walled alluminum nutserts I have at work. Check out the pics below.......The top ones are the "supplied" hardware and the bottom is what I used.
Here is a pic of my nutsert installed..........It doesn't look like it's on very well but, trust me it's not going anywhere.
