Review on Industrial Iron Pipe Shelf Wall Mount: Farmhouse DIY Open Bookshelf for Kitchen Bathroom, Living Room Storage - 2Pack of 5 Tier Pipe Shelves by Michael Boonme

I mounted this on a wooden wall. I started using the screws that came with it, but stopped as soon as I started breaking the screw heads. I went with the smaller screw but remember I was fitting this shelf into a wooden wall. I also flipped the shelf off the floor up. Suggestion to collect it first. Use a spirit level when attaching the shelf to the wall. I screwed a bolt into each flanged tube until it lined up, then screwed in the remaining holes in the flanged tube. I noticed that one of the flange tubes didn't have a screw hole. I'm glad it was down. Normal product for the price. It wasn't hard to collect all this in one boutique for 30 minutes. Now I have to do the shelves, it takes longer. I put 4 because of quality issues.
