Feature Summary

• Continuous hinge door design with three-sided clamping mechanism for secure sealing
• Seamless construction with continuously welded and ground-smooth seams
• Watertight foam gasket ensures tight seal against environmental ingress
• Padlockable security via integrated hasp and staple

Applications

• Housing sensitive electrical components in indoor or outdoor environments
• Enclosing industrial controls and drives
• Protecting additional equipment requiring NEMA Type 4, 12, or 13 protection

Procurement Notes

Verify the specific NEMA rating requirements against the official datasheet before procurement. Confirm that the wall-mount configuration and external mounting flanges match the installation site constraints. Ensure compatibility with existing cable entry points, as this model specifies no pre-drilled knockouts. Check for any regional certification updates regarding UL-50 and UL-50E compliance.

Selection Notes

Select this model when high ingress protection is required for both indoor and outdoor use. The Type 4 rating indicates suitability for hose-directed water exposure, while Type 12 covers indoor dust and dripping non-corrosive liquids. Consider the continuous hinge for durability during frequent access compared to quarter-turn latch alternatives. Verify space requirements for internal component layout within the 20x24x8 inch volume.
