Hey CarFlip Side, I honestly did design it. I work at a place were all the parts we use are Laser cut from sheet steel, up to 1.5" thick. And being in the engineering department, I have some contacts, as well as some welder friends at work also. So, whenever an idea comes to mind, as this one did, it evolves fairly easily. I'm a designer with CAD (Computer aided Design) so I can draw up just about anything imaginable. And I do, we (the designers) are given the opportunity to be creative & that's what makes my job interesting.
Part of this design is the easy installation, usage, and removal.
See ya.
