Installation Notes

Masonry drilling is typically performed by electricians, plumbers, or HVAC technicians when anchoring equipment or routing penetrations through masonry substrates. Always wear appropriate eye and respiratory protection when drilling into masonry, as dust and debris are produced. Confirm the drilling surface is free of embedded conduit, rebar, or pipe before starting. Use the appropriate hammer or rotary setting on the drill for the substrate being penetrated.
