Review on OneTwoFit Adjustable Doorway Pull Up Bar, 25.6-33.5 Inches Length Home Gym Exercise Chin Up Bar HK664 by Jared Winebrenner

This product will only work where the door frame and door jam are next to each other. Most doorframes (as mine are) are installed with a small gap between the door frame and the door jamb (about 1/4 inch gap). This allows an installer to adjust fit. Because of this gap this pull up bar cannot be properly secured to hold full body weight. If you rotate the bar to make a tighter grip you ultimately crush the wood of the doorframe breaking the wood and having to replace the door frame. If you try to screw ends in place the result is the same except you now have screw holes. If u buy u will need to build your own rack and bolt it down.
