The SignalWorks standard

NO SHORTCUTS
BEHIND THE PANEL.

Good electrical work is more than making something turn on. Routing, protection, connections, serviceability and final fit all matter. We build systems that look intentional and hold up to the way you actually use them.

  • Wiring-condition inspection
  • Fault tracing and circuit repair
  • Custom routing and integration
  • 3D-printed mounts and fabrication

One shop. Built around the problem.

SCAN IT.
MODEL IT. MAKE IT.

When an off-the-shelf part does not fit, we use wireless handheld 3D scanning and in-house printing to create a purpose-built mount, bracket or enclosure.
