Okay…so I have to confess…I purchased 2 of these…with NO intention to use them as they were designed…I just wanted to make my life easier with the project I was working on.  But BEFORE I modified them, I assembled them as they were intended…they were GREAT…easy to assemble and I was really pleased. Then I took them apart and modified them to fit my project! 
Just gonna say…I thing it worked out well!
