The product type determines the bracket and fixing arrangement. Send the exact model and all supplied components. A rod kit and a curtain track are not interchangeable systems, and missing brackets should be resolved before their installation is scheduled.
A painted wall surface does not reveal all of the construction behind it. Share any known wall details and nearby services. Installation depends on suitable support and safe fixing locations, not simply finding a plug that fits an existing hole.
Heavy curtains can place different demands on the supports from lightweight fabric. Include product weight information rather than only the window width. The rod span and manufacturer bracket spacing also matter when deciding whether the intended arrangement is suitable.
The agreed service covers non-powered rods/tracks, compatible brackets, positioning and operation checks. Exclusions: Electrical motors/wiring, unsuitable substrates, unassessed cord hazards, unsupported high access.
