Triple track is sometimes used with 3 and 4 panel slider units. Unlike the double track it allows all panels to go to the wall allowing greater access to the closet opening. It does require a jamb depth of just over 5 1/4" to work effectively. The triple track includes the bottom track, which is a one piece track with three roller guide channels while the top track is an additional single guide channel. If you purchased a door you will use the double top track that was included and put the single guide track behind it. If you do not have our double top track you must buy the double top track to go with this. The track comes in chrome and has a 4' minimum order.
Over 72" will ship as two pieces, due to shipping limitations.
