Installation Tips

• Check the track before you fit. File any burrs or flat spots smooth — a damaged track will chew out a new roller within weeks.
• Clean all grit and old grease out of the track. Grit is what kills a roller, not load.
• Replace carriages in pairs. A new roller running against a worn one carries uneven load and both wear out early.
• Measure the old roller before ordering — the replacement has to match on outside diameter and overall width.
• Match the tread profile and the axle as well. Flat, concave, convex and V-groove wheels are not interchangeable, and the bore or screw fixing must suit the existing housing.
• Slide the door through its full travel before refitting stops or screens.

Care & Maintenance

• Use a dry lubricant only — silicone or dry PTFE. Oil and grease hold dust and grind the roller.
• Sweep the track out every few months, more often in coastal or dusty areas.

Warranty

10-year warranty. This warranty is in addition to your rights under the Australian Consumer Law.
