Custom Electrical Enclosures Built to Your Specifications
Klassen Custom Fabricating builds electrical enclosures that meet your exact needs. We create enclosures in any shape, size, material, NEMA rating, and paint color. Our electrical enclosures serve companies across Windsor, Ontario and North America.
What Sets Our Electrical Enclosures Apart
One-Piece Construction for Superior Strength
We build our custom electrical enclosures with one-piece construction instead of add-on components. This design choice creates a more rigid unit that performs better in industrial environments. The one-piece design also reduces potential failure points and extends the enclosure’s service life.
CSA and UL Approved Protection
All our custom electrical enclosures meet strict certification standards:
- CSA Type 12, Type 4, Type 4X approved
- UL Type 12, Type 4, Type 4X, and Type 3R approved
These certifications ensure your enclosures provide proper protection for your electrical components against dust, water, and other environmental factors.
Ready for Final Assembly
We supply your custom electrical enclosure ready for final assembly. Your enclosure arrives with:
- Door hardware installed or supplied loose per your requirements
- Document pockets mounted where specified
- Windows placed according to your design
- Gaskets installed for proper sealing
This preparation saves you time and ensures correct installation of all components.
