I have not seen in commandachet Prior. Big mistake! But ... When a flight has achte as rf. "4U" is expected to cram four rack units in it. H no, because the grip holds the indoor and 1 U it remains that you use 3! I do not blame Stagg fun stuff that makes the right price, but I find more honnte from them to call this the rf "ABS-3U / T" instead of "ABS-4U / T ". Apart from a, aa looks nice ... for the price ... I did not balad so I will not comment further on the solid but looks quite aa rsistant ... for the price
