This file is a 'builders pack' of six cab guards, typically called headache racks, used in the Pacific Northwest lumber industry. They are the typical round tube '7' bar, and have been sized to correctly fit the Tonkin (TON) 87th line. This file has passed the normal software checks, but should there be an issue, contact me via the designer link, or via email direclty to Steve Nasburg. My email is: modelmechanic@gmail.com
