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.
• Fit the rear carriage first, then set the front carriage to get your clearance.
• Adjust last to bring the door parallel with the jamb, working from the handle side.
• 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.
