This is one of those reviews that makes me chuckle. The first time I used a product like this, I was fifteen, and now I'm seventy-five. So you must think I like the product, and you would be correct. They are easy to install using a stud finder, and the Ryobi battery drill is a God's send. The are in a niche and the four foot shelves fit perfectly with four uprights as recommended. Easy up and good looks, and I know they will last.
I needed some quick shelving in the garage for light items. These uprights are the right strength and can fit standard shelf supports which are good for 6 to 12 inch shelves. They are good enough for light-duty shelving and light weights. I needed shorter uprights so I cut them in half and anchored them into studs through sheetrock. I am a big fan of anchoring these supports solidly - not a fan of sheetrock screws (personal preference). Would not use these for heavy items unless the load can be spread out evenly. For heavy uprights, go for the double-row uprights for wider shelf supports.
I too am looking at these nifty bow-tie anchors and I challenge anyone at Rubbermaid to figure out how they are supposed to be put thru a 1/4 inch diameter hole without destroying your wallboard. I am a veteran of wall shelf systems but this one has me stumped. Using the pin or scrunching with fingers or tools. I don't get it. Better make a video of this one when you figure it out.
