Other than the ProStar Welding Wire Conduit https://www.praxairdirect.com/Industrial-Gas-and-Welding-Information-Center/Cutting-Tips-Tricks-and-Information/ProStar-Welding-Wire.html  and Wire Wizard https://www.wire-wizard.com/guidemodule.htm, anyone know of an affordable system to remove restriction from GMAW liner runs at corners? I thought I could find more on the marked than just 2 options but nope.

Any help is much appreciated.
