Our I-Semble Rolling Door Hardware features sealed ball bearings for glassy-smooth rolling action, and is available in several roller styles and finishes to match your decor. The track is made of solid 1-1/2''H x 1/4'' thick flat steel for excellent beam strength and minimal projection from the wall. A dovetail joint in the middle of the track provides a strong mechanical interlock, and allows you to add optional lengths of track to customize the track length. Also available is a soft-close option (#51786, sold separately), which engages at the final section of travel to pull the door quietly closed.
