I'm hoping to hang two sections of IKEA's [Kungsfors](https://www.ikea.com/us/en/p/kungsfors-wall-grid-with-storage-stainless-steel-ash-s49254335/) system on drywall in our kitchen. It'll be about twice as tall as the one in the link (two sections), but since they're independent of each other the height probably doesn't matter.

The uprights/suspension rails are [here](https://www.ikea.com/us/en/p/kungsfors-suspension-rail-stainless-steel-80334858/). Each has three mount points on it, which you can see on page 7 of the [assembly instructions](https://www.ikea.com/us/en/assembly_instructions/kungsfors-suspension-rail__AA-2051144-1_pub.pdf).

**The problem** is that I can't align any of the uprights with a stud. Even if I could it'd only work for upright, since the shelves are 23" and studs are 16" apart.

So! Will the 3/16th inch version of [these snap toggles](http://www.toggler.com/products/snaptoggle/overview.php) work, if I use them for all 18 mount points? (3 per rail x 2 rails per column x 3 column) Or is the drywall just gonna crumble?

It was also suggested that I run a 1/2"-3/4" board horizontally, attach that to the studs, and then attach the Kungsfors suspension rails to the board. (Like you would for hanging cabinets I guess. (Is that what I need to do? Or will the snap toggles be enough?

Thank you!
