I own what I thought was a standard SKB 4U roto rack -- standard depth, molded-in handles, hinged lid on one end and "dust cover" (with red plastic hinges) on the other, top and bottom profile similar (identical?) to the older SKB racks (i.e., not an "X" pattern). But when I go to the SKB website, what they show as the roto rack is completely different: hinged on both ends, with an "X" pattern like the shallow SKB racks. SKB Roto Rack Is this a new version of the roto rack? Are they generally available? Has anyone tried one?
