These are 90-degree holders that can be used to make a U-holder, diagonal holder, or makeshift box. I've also found myself using these holders in combination with universal holders for some tools. These are great for storing large tools to keep them in place. They come in an 8 pack.
I discovered the Tool Grid system while running around SEMA. When I saw it, I knew it was going to change the way I looked at tool organization. Foam is great, but if you replace a tool or get rid of one, you have to redo the drawer with an entirely new piece of foam which is very time-consuming.
This is where Tool Grid by Mantis comes in. Because the entire system is modular, it's extremely easy to add and take away tools just by swapping a few pieces out. It also improves your ability to lay tools out. Instead of just laying tools flat, it gives you the option of storing tools vertically which opens up a lot more storage space.
While Will and Chris were down at my wash-bay demonstrating every aspect of the Tool Grid system, we were able to consolidate two wrench drawers into one. It really got my mind racing on just how organized and efficient my drawers could be.
