$40! Forgive me; I don't have a video to go with this...
But if you want to place a rack at your feet, instead of off-stage, or precariously on an amp; then there is a much cheaper and readily available device available called... the floor!
Also... If you really need it to be at a 5 degree angle you could lean it against an equally cheap and readily available device called 'a wall'.
Alternatively, if you want something that looks and works exactly like this then get some rack rails, hit it with a hammer until it is the right shape and then paint it black.
Total cost $10. And that includes the cost of the hammer.
Perhaps I should book a stand at NAMM selling my device for angling gear at precisely the right angle... which I call... the small pile of beer mats?
