Review on 🔌 Slide-Co 243423 Peg: Clear, Pack of 6 - Self-Locking Shelf Support Bracket, 1/4" Thickness, Easy Installation with 1/4" Diameter Hole & 3/4" Wooden Shelf Compatibility by Michael Maes

I ordered these 6 packs hoping to only use 2 to replace my current cleats. The shelf support is slightly offset from the pin on my old clips - see picture. You need to replace all the supports, not just one, to level the shelf. As a result I got 5 pins, four corners and one central bar. The pen was also significantly larger than my old ones. My first impulse was to drill big holes in my cabinets, but as this is a permanent change I took my dremel and sanding wheel and after about 15 minutes shaved them down to match the size of my holes. Generally they do the job but I had to replace 5 instead of one and move the entire shelf down one tier as it was taller than before due to a different offset. If you have more than one set of broken stud cabinets, you may need to order multiple packs.
