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.
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.
Provide the television model, mass and mounting-hole specification together with the bracket model. A bracket advertised for a screen size still needs compatibility checks. Do not assume a reused mount will suit a new television because its diagonal measurement is similar.
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.
