• Overall size: 21.9 x 27.3mm

Installation Tips

• Clear the top rail cutout of dirt and file back any burred edge before fitting — the guide will not seat flat on a damaged rail.
• Seat the guide fully into the rail so the body sits flush with the top of the door, then fix it off.
• Slide the door through its full travel and check the guide holds the top of the door without binding.

Care & Maintenance

• Wipe the guide and the channel it runs in clean every few months — grit packed into the channel is what wears a guide out.

Warranty

Covered by our 12-month warranty and your rights under the Australian Consumer Law.
