PATCH PANEL 01 · LOW VOLTAGE · CCB #249201 · MILWAUKIE, OR Knepper moves information
Commercial low voltage, done to spec, by a licensed crew led by a technician with twenty‑two years in the trade. One cable run starts at this panel and ends at every drop in your building — follow it down the page.

Nine circuits,
one licensed crew.
Every service below is run by the same crew to the same standard: pathway, pull, terminate, test, label. Pick the one you came for, or bundle them — most buildings need more than one and they are cheaper to pull together than to come back for.

Everything on this wall
is the same trade.
Whatever the plate says on the front, the work behind it is the same trade: pathway, pull, terminate, test, label. Below is one wall in elevation — every device drawn at the height it actually gets mounted, and every one of them fed off the same tray.
- Smart office One crew wires the whole connected office.
- Cameras / CCTV Cameras that are still recording when you need them.
- Fire alarm A life-safety system, wired by a licensed crew, inspected like one.
The run enters here.
Then it goes everywhere.
The rooms this work is built for are the technical ones — satellite centres, operating rooms, cannabis-facility security and lab compliance. One closet on the ground floor feeds all of it — every camera, every reader, every access point, every drop on every floor.

This is what the wall
looks like when it is done.
Every screen is a photograph from a real Knepper job — the same monitors that go in at the end of a security install, running the work instead of the building. No stock photography anywhere on this site.

Low Voltage Solutions · Milwaukie, Oregon
Five kinds of room.
Five kinds of drop.
The markets on the van, and what the low voltage scope actually looks like once you are inside each one.
- Commercial Offices and tenant improvements: data and voice at every desk, access points in the ceiling grid, cameras on the entries.
- Industrial Warehouse and plant: long runs, fiber between buildings, cameras over the dock doors, hardware that survives the floor.
- Retail Storefronts and multi-site rollouts: register and back-office drops, one rack that looks the same in every location.
- Education Campuses and classrooms: a drop at every board and clock, an access point per room, readers on the exterior doors.
- Healthcare Clinics, care facilities and OR suites: cabling for systems that cannot have an off day, readers on restricted doors, work done around occupancy.

PUNCH LIST · QUESTIONS TO CLEAR BEFORE THE JOB
- Do you work with general contractors and IT firms?Constantly. Most of our work comes by word of mouth from IT providers, general contractors and property managers who bring us in for the low voltage scope. We are used to working alongside other trades and to somebody else’s schedule.
- Do you do residential?Our specialty is commercial and industrial installations. Tell us about the project and we will say honestly whether we are the right fit.
- Do you work in hospitals, data rooms and cannabis facilities?Those are exactly the buildings this trade exists for: operating rooms and satellite centers where the low-voltage systems cannot have an off day, and cannabis cultivation and retail sites where security and lab compliance are part of staying licensed. Tell us the building type on the walkthrough.
- Are you licensed in Washington too?We hold Oregon CCB #249201, Oregon electrical licence 4911LEA, CLE723 and Washington licence KNEPPJK854KK, with $2,000,000 in liability insurance and a $50,000 bond.
- Can you take over a job someone else started?Often, yes. We walk the site first and tell you what is reusable and what is not before quoting anything.
- Do you serve my city?Based in Milwaukie, working the Portland metro — Portland and Clackamas County by default. Not sure about yours? Ask.
- What are your hours?We’re on call 24/7 — off-hours and weekend installation is normal in occupied buildings.
- How do I get a quote?Book a walkthrough. We look at the building, then you get a written scope and price you can compare against anyone else’s.
