A mounting system for a physical therapy device that allows the physical therapy device to be anchored at a desired height. The mounting system includes a top bracket and a bottom bracket that each can be received over an edge of a door. A slide rail extends between the top bracket and the bottom bracket. At least one attachment block is received on the slide rail. The attachment block can be moved along the length of the slide rail and includes an attachment ring, or similar device that allows a physical therapy device to be attached to a stationary point. The mounting system can include a second attachment block for providing additional points of attachment for the physical therapy device.
