It doesn’t stay in
The pipe keeps coming out. Not worth the money. Not sturdy to hold a top table.

Good finish, poor hardware.
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.

Lovely and sturdy for what I needed!
Size: 3 Set 4-Tier, Planks Not Included, Size: 3 Set 4-Tier, Planks Not Included
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!
