A large screen needs suitable handling space and a clear route to the wall. Mention stairs, tight rooms and fragile surroundings. Screen size and access help plan the job; the customer should not be expected to improvise unsafe lifting assistance.
Mechanical wall mounting does not include adding power points, concealing wiring inside a wall or relocating electrical services. Explain the existing power arrangement. Any separate electrical or cabling work must be arranged with the appropriate trade before assuming a finished installation plan.
A moving bracket can place different demands on its supports as it extends or turns. Provide the full instructions and intended movement. Its load rating and the wall attachment both need review; screen weight alone is not the complete assessment.
The agreed service covers product/weight/bracket/substrate review and mechanical installation where suitable. Exclusions: Power points, in-wall wiring/cabling, electrical work, structural alteration, unsuitable mounts.
