I have a few oddly shaped gear pieces in my rack. Up until now they've been sitting on sturdy rack pieces that could act as shelves. But that limited the way I could "furnish" the racks and I bought a couple of these instead.
They proved to be a very good addition and were far more sturdy than expected. Simply solid, reliable contruction. The various holes in the shelf lets you secure basically anything with a hole underneath.
The rack looks more tidy and I don't have to think about which units are stacked on which when something is removed for service or if stuff are sold or new gear bought.
I will probably get a few more with my next order.
