It is good of you to bring that picture here. My purchase was for one complete system that goes up to 20 ft. I will only build up as high as in your picture for now since the Winter is here, and do the rest in the Spring. I didn't ask for any piece or part apart what was in the pre-arranged system. These are the components of it that is as advertised in their website and have received all of them, can't see anything like "clamps" among them:
20' Rolling Scaffold Tower
Features
6 - PSV-432 - 5' x 6'4'' Double Ladder Frame
6 - PSV-304 - 7' x 3' x 4' Tube Cross Brace
8 - PSV-104 - 9" Coupling Pin w/ 1" Collar (#7)
16 - PSV-112 - Toggle Pin
8 - PSV-113 - Spring Clip
3 - PSV-1100 - 7' x 19" Alum/Plywood Deck
4 - PSV-503 - 7' Tube Guard Rail
2 - PSV-525B - Mason Frame Access Panel
4 - PSV-150 - 8" Locking Caster w/ 1 3/8" Stem
1 - PSV-1202 - 5' x 7' Diagonal Gooser (Yellow)
It came without any manual or instructions, I called them but they don't have any either!
I very much appreciate your help.
