Mine are designed similar to others that companies that also make them that require no welding at all. I have never seen the style that PES makes, so I can't say what is required to be able to use their brand. But like Larry mentioned, I have also heard they require welding for installation, so making a version that will allow them to be installed without welding, or even any machine work, as mine are, is going to increase the marketing potential, I think, because of the greater ease in which they can be installed by the end user. Also, patent protection will also be an added feature incorporated into mine, so before this product will be revealed, that will be in place first.
