The Harbor Freight Tubing Roller offers unbeatable value, but it has plenty of room for improvement—starting with the SWAG Weld-On Wings. This upgrade reduces the effort required to roll tubing by roughly 50% by extending the width of the bottom rollers by 6" or 12", giving you greater mechanical advantage. If you’ve ever struggled with 1.5" or thicker-wall tubing, these wings will transform your roller into a much more capable and enjoyable tool. The kit includes four 3/16" steel wing extensions and four 1/4" steel spacer plates, and installs easily without disassembling your roller. Note: Harbor Freight Tubing Roller is not included.
