The Carbon Grab Bar is a new leverage point for windows. It is 10 inches long, 1.25 inch diameter and has about 8 inches of work space. This has a PVC coating to keep the bar from being too slick to work from. Hang this in between the door and the roof weather seal. Place it once and you will not have to move it like a window ring till you are finished with the section of the roof. Get two for a sedan and speed up your pace on a roof by not having to readjust leverage points. The grab bar now comes with removable pins so the straps can be replaced if needed. NO TIPS COME WITH THIS.
