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.

Lovely and sturdy for what I needed!

We LOVE these shelving brackets! We were moving our books from our office space to turn that room into a nursery and I needed something that would be sturdy and off the floor since my books were moving to our living room. These are extremely sturdy, and also go with our curtain rods and other furniture that has this industrial style. The instructions for assembly are simple and easy to follow, I would just ensure you have an extra set of hands (this isn’t a one person job) we ordered the 3 pack, but ended up only needing the two for the space on the wall and they still hold the weight well. Also this is a work in progress so please disregard that I don’t have the other two shelves here😂 Definitely a high quality and great looking alternative to some other brackets out there!

Takes time to install right.

Saw a few complaints about this product in the reviews before ordering but gave it a shot anyways. Took a little longer than I would have liked to install, but was only time consuming, not difficult. I made sure at least 2 screws on each base plate were into studs so it's more than sturdy. Hung each of the 3 brackets by 1 screw, marked the rest of the holes, took it back off the wall, installed anchors where needed, and finally screwed each back up fully. And for the people saying that the threads don't line up once snug, try switching out a fitting or pipe so it's a different thread mesh. If that doesn't work, just over tighten the fitting. Furthest one I pushed was nearly 3/4 of a turn past finger tight. I don't have a single loose connection on the whole shelf. My wife can't wait for us to go to lowes tomorrow for the wooden shelves to finish off the bookshelf this will be for her.
