Existing electrical boxes may need extensions so the device remains properly positioned at the new wall surface. Large slab openings are carefully planned to reduce cracking during fabrication and installation. Outlet placement can interrupt dramatic veining, so layout approval is important. Electrical work should be completed by a qualified professional when boxes or wiring must be moved.
Key considerations
- cutout durability
- installation accuracy
- electrical safety
- custom openings
- matched cover plates
- continuous slab design
