Multi-pass sliders. Ceiling and floor track (multi-pass sliders). Here again we see the popular Hawa Junior track from Häfele used for the top track, but with multi-pass sliding doors you also need some means of keeping the bottom of the doors in line and sliding as you’d expect. This usually means a floor track or guide to hold them in place. Floor guides can be a tripping hazard and can collect debris, so lower trafficked areas are best suited for this type of application.
Room separation: This project used a track system by Häfele America Company called the Hawa Junior, which is a favorite of architects. The track is made from extruded aluminum, which is stable, uniform and lightweight. The trolleys roll on two nylon wheels with ball bearings — a combination that makes for low rolling resistance and quiet operation.
Slider doors. Johnson Hardware makes a slightly more cost-effective alternative to the Hawa. I used its heavy duty track system on the pocket doors in my own home. It’s also made from extruded aluminum, which ensures a uniform and even rolling surface. Also, note the four wheels on the trolleys. You’ll often see trolleys that have three wheels on lower-quality sets; four is better because it ensures a more even rolling surfa
