Premium Equipment Starts With a Clean Design
Cornerstone Pro designs and hand-wires control panels, depth & encoder systems, and wiring harnesses for oil and gas field equipment — every terminal labeled, every circuit tested, every unit built in Calgary.
Our mission
We build oil and gas field equipment that holds up to the work it's asked to do. That means engineering it with the same care whether the job is a two-wire harness or a full skid rebuild — laid out clean, labeled clearly, and tested before it leaves the shop.
What we build
Four kinds of work make up most of what comes through the shop.
Control panels
Custom-fabricated panels — fuse blocks, switches, meters, and terminal strips laid out and labeled to spec.
Depth & encoders
Splitter boxes, rotary encoders, and measuring-head electronics, reconditioned or built new.
Harnesses & breakouts
Hand-terminated cable assemblies and breakout boxes built to route cleanly through a rig or skid.
Testing & repair
Continuity and voltage checks on everything that ships, plus fault-finding on existing systems.
Recent work
A few pieces that have gone out the door.
Splits a Linewise depth signal to an encoder and a customer's KWAT input.
Ground, encoder, tension and slip-ring circuits, each labeled at the block.
Selects shop or rig power between two sources, with dual voltage metering.

What we build, wire, and fix — from a single breakout box to a full skid.
Custom control panel fabrication
We design and build control panels from the enclosure up — fuse blocks, switches, meters, and terminal blocks laid out, labeled, and dressed for a panel that's easy to service later.
- Enclosure layout and drilling
- Labeled terminal strips
- Panel meters and switching
- Built to your spec, or ours
Depth measurement & encoder systems
Splitter boxes, rotary encoders, and measuring-head electronics for depth and tension systems — reconditioned or built new. We've worked on gear from Century Geophysical, Linewise, and other wireline equipment makers.
- Encoder reconditioning and bench testing
- Depth splitter boxes
- Tension and slip-ring wiring
- Compatibility with common logging systems
Custom cable & harness assemblies
Hand-terminated harnesses and breakout boxes, built to route power, signal, and ground cleanly through a rig or skid.
- Multi-pin connector termination
- Braided and armored cable assemblies
- Labeled breakout boxes
- Solder and crimp termination
Skid & vehicle electrical builds
Full electrical builds for skids, service trucks, and logging units — from the main switching hub down to the last light switch.
- Main switching and fuse hubs
- Interior and exterior lighting circuits
- Camera and alarm wiring
- Shop / rig power switching
Testing, diagnostics & repair
Every circuit gets checked before it ships. And if something in the field stops working, we can track it down and fix it.
- Continuity and voltage testing
- Fault-finding on existing systems
- Component-level repair
- Bench testing before install

About Cornerstone Pro
Cornerstone Pro is a Calgary-based shop that designs, builds, and repairs the electrical systems oil and gas field equipment depends on — control panels, depth and encoder systems, wiring harnesses, and full skid builds for wireline and logging operations.
Every panel starts on the bench: laid out, labeled, and wired by hand, then tested before it goes anywhere near a rig. That's the standard whether the job is a small breakout box or a complete switching hub.
We're based in Calgary, Alberta, and work with operators and service companies across the field.

Labeled, not guessed
Every terminal and every wire is labeled at the block, so the next person who opens the panel knows exactly what they're looking at.
Tested before it ships
Voltage and continuity get checked on the bench before a panel or harness ever leaves the shop.
Built for the field
Sealed connectors, dressed conduit, and enclosures chosen to hold up on a rig floor, not just on a shelf.
Control panels, depth & encoder systems, harnesses & breakout boxes, and skid or vehicle electrical builds.
Wireline and logging operators, service companies, and field equipment owners.
Based in Calgary, Alberta — shop builds and on-site support.
