With this 1" door track tweakster the user is able to repair crushed, roll-tip trailer door tracks. The Tweakster is a hand tool that's hammered through crushed track to open it, but a machined slot in the tool can also be used to tweak the track edges back into shape. Tweakster repairs take minutes and can be done on the trailer. This is made to be used on the Todco trailer tracks. We also offer this tool for 2" tracks on Whiting trailers.
