About ArcLine Assemblies

ArcLine Assemblies is a Washington-based assembly shop focused on building high-quality cable and wire harness assemblies with fast, dependable turnaround.

We’re starting with the fundamentals that matter most to engineers and operations teams: clear communication, clean workmanship, and repeatable processes. That means build-to-spec assemblies, consistent labeling and documentation when required, and quality checks that are designed to prevent surprises downstream.

ArcLine is being built for teams that move quickly—product development groups, integrators, and manufacturers who need a partner that can keep pace without sacrificing reliability. As we grow, our goal is simple: become the shop you can send an RFQ to and trust the outcome.

Coming soon. If you’d like to connect early, reach out and tell us what you’re building and what you need.
