Any standard wood doorframe* can be your center for inversion with the EZ-Up^TM Inversion Rack. 

Without interfering with the normal use of the door, quick-disconnect locking brackets secure to the doorframe and allow the Inversion Rack to be installed in just seconds.  

Easy-reach handles and comfortable foam handgrips allow for mounting and dismounting with ease.  The double-bar system enables you to hang freely out and away from the frame - allowing for maximum mobilization during your inverted workout!
