After fitting, the panel height needs checking against the opening and compatible hardware. Excessive adjustment is not a cure for an unsuitable part. The aim is supported travel and workable clearances, with any remaining frame or track limitation explained before handover.
Check the accepted panel through its ordinary movement after replacement. Stops and closing alignment should be considered alongside the rollers. The task does not include powered operators, access-control integration or certification of a specialist door system.
A panel can have more than one roller assembly, and the condition of each matters. Discuss whether compatible assemblies need replacing together. Replacing only an obvious damaged wheel may leave an uneven panel if the other support is worn or cannot be adjusted correctly.
Replace accessible compatible roller assemblies on an accepted panel, set the height and check ordinary travel and stops. Scope limits: Ordinary non-powered safely handled panels only. No heavy specialist lifting, glazing work, powered operators, structural changes or access-control integration.
