I bought one of these last time it came up on woot, though it was the smaller 2 panel version. Finally got it installed last week in the basement. It was super easy to install once I found the studs in the wall, and it’s far studier than the fiber peg board in my garage. The slotted fasteners are more secure than the standard peg accessories, but you’re going to need more if you want to utilize all of your space. I was able to hang a heavy hammer drill, 24" crescent wrench and a bunch of other tools without issue.
I’m tempted to order this to fill more empty space on my basement wall, now to convince myself I don’t NEED it.
My only issue with the unit was that the bin hanger wasn’t included with more order, so the 3 hanging bins are just sitting on the workbench nearby lonely and sad they can’t join the party.
I’m sure you could mount these to cinder block or concrete wall with TapCon screws (the blue ones). But it will leave no back room for the pegs to go through - so you might have to install with spacers.
No spacers will be required. The flange around the edge of the panel will space it away from any flat surface. Just use the Tapcon or any other good concrete anchor.
