I have run out of floor and bench space and it's time start filling up the racks I have stored away. :-(
Unfortunately most of the equipment does not have mounting ears. Last time I looked at them they are hard to find and very expensive.
What's everyone thoughts about using 4 post ventilated shelves like this?

They are rated 120 kg a shelf.
I can source them locally cheaper and faster than a set out mounting ears on Fleabay with shipping. And I can adjust the height instead of getting multiple sizes of ears.
It's also easier to wrestle something on a shelf than mount it in a rack with screws. Or at least that is my limited experience.
And If I want put another piece in rack it seems easier.
What do the experts have to say?
Thanks
Dave?
