Square Box Custom Electrical Enclosures
Specify sealing targets clearly before a custom enclosure quote
Use this comparison when a buyer, engineer or panel shop needs to state sealing expectations clearly before a custom enclosure quote.
Rating targets influence material, gasket compression, cutouts, cable entry, finish and testing expectations. The RFQ should describe the application environment and acceptance requirements without assuming unsupported certification claims.
| Target | Usually points to | What to state in RFQ |
|---|---|---|
| NEMA 4 | Indoor / outdoor protection against windblown dust, rain, splashing water and hose-directed water | State water exposure, cable entry direction, gasket path and finish requirements. |
| NEMA 4X | Sealed enclosure needs with added corrosion-resistance expectation | State stainless grade or corrosion environment, washdown notes and hardware material. |
| IP65 | Dust-tight and water-jet oriented ingress target | State the IP target, cutout details, gland approach and whether project testing is required. |
Built for NEMA-style and IP-rated applications. Final rating depends on design, materials and testing requirements.
Square Box provides custom enclosure fabrication, component mounting and customer-BOM assembly support. Final electrical listing, field acceptance and project compliance depend on the complete design, selected components, testing and certification requirements.

FAQ
Do not assume a verified rating unless project-specific testing and documentation exist. Use cautious wording until final requirements are confirmed.
Door design, gasket path, hinge and lock compression, cutouts, cable entry, material, coating, welding and testing requirements all affect the final application.
They are different rating systems. RFQ documents should state the project target and testing requirement rather than treating them as interchangeable.
Email and drawing upload are enough to start. Add optional quantity, material, finish, BOM or terminal schedule details if available.
