Does the name Shark Tank ring any bells? The reality TV show features a panel of entrepreneurs who consider offers from businesses seeking investors. Donny McCall first introduced his ingenious Invis-A-Rack on Shark Tank. After the show, Invis-A-Rack partnered with Dee Zee and is now manufactured exclusively in the United States and distributed world-wide. The completely foldable unit is perfect for those who need to haul and park in a garage.
