The top portion of the frame includes a hook-like feature that engages the front and upper surfaces of an upper rung and the lower portion includes a stop that engages the front surface of a lower rung to provide for a middle rung to be located between the upper run and the lower rung. This will provide for the frame to extend the length of three rungs. A support or platform is located on the lower portion of the frame and receives the feet of a user.
