In plain words
The completed installation includes more than hanging attractive panels. It covers removal planning, opening preparation, tracks, sections, rollers, hinges, springs, cables, seals, opener attachment and decorative pieces. Each component is installed in a planned order, followed by alignment and operating checks. At handover, the homeowner sees how the door moves, how the emergency release works, which routine care applies to the finish and hardware, and what product information should be kept for later reference.
