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.
• Match the new roller to the old one for wheel diameter and profile — concave, convex, V-groove or flat.
• Check the axle pin matches too — same diameter, same length and the same fixing type as the roller you removed.
• Slide the sash through its full travel before refitting stops or flyscreens.

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
