Question: Do the shelf brackets have mounting holes to mount to the wall and the shelf?
Document: Love the design and look, I ordered two packs for a total of 4 brackets. The brackets and location of the screw holes were slightly off (length wise). It's manageable, otherwise great look!
These are substantial, welded (I'd guess hand welded on a jig) and decorative brackets. I had asked a question before I purchased and every response said that I'd love these brackets; and, indeed, the crowd was absolutely spot on! Used them to bolster a shelf overhanging my loft so that I could store books on it. Worked like a charm: you can dance on that shelf! The price was competitive and the artistic design superior - gives you value for your money!
LOL think these wear more than the shelf I'm putting on them .... they ate sturdy to say the least.... haven't put em up yet so will have to get back to tell you how tey work
The design is very nice and the finish actually a flat black, unlike the glossy black as it appears in the picture. A big negative...the brackets are shipped with chrome finished screws. Really? Against black metal? Why not just provide the black screws as anyone buying these would want? ?
This item matched perfectly with the existing collumns that we had. The look and feel of the bracket was exactly as I imagined.
Just needed to realize that there are two to a package. Ended up with extra but like the look enough to do again in my office
I wasn't sure what to expect. I was going by what other reviewers had said. These are quality built. They are sturdy and I like how there is a hole on the top and the side to screw to wood or whatever. I am happy with my purchase. It's also great that you get 2 for the price.
Answer: yes
