Set screws are poor quality and are sometimes powdercoated on the exposed threads. Leads to striped hex sockets and inability to tighten properly. Durable finish as evidenced by no visible damage after throwing parts across the shop in frustration. Ended up running self tapping screws thru parts to complete assembly.

Kinda flimsy…

Thought the assembly was metal, it’s some kind of PVC.

Quality pipes for a good price

Size: 42inch Tall (NOT included wood planks), Color: Black

This item is just as described. It is the pipe fitting portion of a 3 shelf unit. You must buy your shelving separately once the rails have been installed. Purchasing the pieces this way was much more cost-effective than separately buying each part from the hardware store, and all the pieces were clean and ready to be mounted unlike the pieces from the hardware store. It was moderately difficult to hang, since you are trying to keep everything very level. I imagine the distance between each rail will be a factor in how easy this is to level. The difficulty may have also stemmed from the fact that we were mounting it in a small toilet room and had little room to maneuver during the installation process. Still, it is a good product and we are considering purchasing a second one for another location in our home.
