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 an acetal roller, not load.
• Replace both assemblies together. A new roller running against a worn one carries uneven load and both wear out early.
• Compress the spring to seat the assembly into the top channel, then let it take up against the track.
• Check the door hangs parallel with the jamb before you let the spring settle.
• Slide the door through its full travel before refitting stops or the closer.

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.
