METALTECH AL-Q0105 Scaffold with Guardrail,EasySet,Alum,6ft

I am very happy with this purpose.1) The cross bracing latching I did not catch onto immediately but once I understood the spring loading claw action and how to control it, putting together and dismantling became a breeze.2) Because of this being made of light weight aluminum, it can be very dangerous trying to climb up from the outside of the structure. The whole structure can topple back onto you easily and more so the heavier you are. This leaves you having to climb up from the interior of the structure and why there is a hatch door on the standing platform.3) I now would like to add to this scaffolding to reach up higher. I could not find information about what I needed to buy, so I phoned Metaltech. They emailed me the information about how to do it and they gave me the part numbers to buy. Good customer service from Rebeca who suggested I contact a distribution vendor to get a hold of the parts.4) There are no pictures on the internet of the said parts. I could find only one vendor who listed the part numbers, no photo(s) of what I would be buying, and the pricing looks to be very very expensive.I'll update this review as I progress further...
