Construction record

How the wall is built.

The model decision begins with the wall, not a generic feature list. Confirm the assembly, then move to model-level evidence.

Masonry or concreteTimber studInstallation voidBoard / plateFinished surface
Wall construction What decides the box Box family
Board wall on timber or metal studs Board thickness, clamping method, box depth against insulation Hollow & timber wall boxes
Timber frame / log wall Fixing into timber, conduit direction, depth available in the structure Hollow & timber wall boxes
Masonry / plastered solid wall Drilled opening, plaster thickness, levelling of the mounting face Hollow & timber wall boxes – solid-wall variants
Concrete wall cast on site Fixing to formwork, concrete cover, conduit entry position Concrete & precast boxes

Send a photo of the wall opening and the device you plan to install if the construction is unclear; we will confirm before you order.

For new-build positions, send wall layers, available depth, fixing condition and device system for model review.

For replacement work, send opening dimensions, existing fixing points and cover-frame spacing where known.

Project context

Carry the record forward.

Wall first

State timber, board, masonry or replacement condition before choosing a model. This keeps the enquiry useful to the next reviewer.

Model exact

Check device and cover-frame compatibility against the market and the exact model. Do not infer compatibility from a family label.

06 / Project handoff

Send the wall into the enquiry.

Include target market, wall construction, device system, quantity and packaging. For replacement work, add a photo and opening dimensions.
