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.
Show the full opening and explain the intended mounting position. Handles, opening windows and the depth of the recess can interfere with the curtain or fittings. The final layout should be checked against the product before any drilling is agreed.
Long rods or tracks may require a specific support layout. Provide the manufacturer instructions and desired width. Omitting an intermediate bracket to improve the appearance is not appropriate when the product relies on it for support under normal use.
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.
