A Solid, Stylish Solution!
Size: 4-Tier (Not included planks)
I use this industrial pipe shelf setup in my salon to display and organize products, and it’s been a great fit. The hardware is sturdy and gives a clean, rustic vibe that works well with my space. It was easy to install, and I added my own boards to customize the look. The open design makes it easy for clients to see what’s available, and it’s held up well with daily use. A solid, stylish solution for keeping things neat and accessible.

Easily assembled.
Size: 3Pack of 5 Tier (Not included planks)
Easily assembled, seems sturdy and built to last. Once attached to wall seems even sturdier than expected. Anchor pieces included but I choose to find studs to anchor to.

Good but misleading size
Size: 3Pack of 5 Tier (Not included planks)
Sturdy set for shelving. However dimensions are misleading. Not sure if they sent the incorrect size but the vertical distance between shelves was 11” and that’s without the shelving installed
