When it is not possible or if it's undesirable to flush mount the track and trolley system against the ceiling, you will require some track suspenders. These can be connected using ready rod/threaded rod or cable (pictured to the left) to lower the track beneath girders, ducts, etc. We recommend using one track suspender for every 4' of track length, plus one at each end. To determine how many you will need, simply divide the length of your track (in feet) by four and add one.
