I-Semble Light-Duty Blind Shelf Supports
Gain practical storage space while maintaining a clean, modern look. Once installed, these concealed shelf supports are completely hidden from view, creating the illusion of a floating shelf. They are made of sturdy metal, and are securely screwed to wall studs for a weight capacity of up to 50 pounds per pair of supports. Shelves should be a minimum of 18'' long in order to span two studs. One pair of brackets can support a shelf up to 34'' long. If you need a longer shelf, just add additional brackets.
- Height adjustment slots let you level the shelf if your initial holes are slightly off
- All hardware is provided, including mounting screws—you provide the wall space and the shelf
Another thing I didn't realize from your write up is that drilling the shelf holes would require a drill press. Size required is more than my home drill chuck could accommodate.
One of my mottos is "live and learn" and sometimes the learning part involves a little frustration.
