blind installation can be appropriate when a visible maintenance item is worn, loose, damaged or no longer works as expected. The measured product, mounting style, substrate and complete operating-safety system must be suitable before installation proceeds.
Signs: a bounded task needs a clear decision before work is scheduled or a visible maintenance item is worn, loose, damaged or no longer works as expected. Causes: ordinary use, visible wear or local damage or loose compatible components or incomplete prior work.
A blind ordered for a recess needs more than a rough outside width. Provide the supplier dimensions and opening measurements, including depth where relevant. Installation should not rely on cutting or adapting an unsuitable product after it arrives.
A narrow trim or existing hole does not automatically provide adequate support. Wall construction, bracket loading and safe drilling locations need consideration. Explain known services and restrictions, and avoid removing finishes merely to provide a quotation photograph.
The agreed service covers measured product/bracket compatibility, supported fixing, operation and mandatory cord safety. Exclusions: Electrical motors/wiring, specialist custom manufacture, unsafe/incomplete cord systems, inaccessible work.
