Industrial Flame-Retardant Waterproof Junction Box - Bolt-Fix Type
WBX
Product Introduction
Engineering-Grade Injection-Moulded Waterproof Enclosure
, available in PC, ABS or flame-retardant material with precision one-piece construction. The two-part base-and-lid design delivers IP67 dust and water protection with corrosion resistance, suited for industrial wiring and equipment power distribution.
Bolt-fix fastening ensures a secure, tight seal between lid and base. Built-in PCB mounting screw holes support circuit board installation for real-time monitoring and status visibility. Customisation options include material upgrades (UV-stabilised, flame-retardant, GF-reinforced, etc.), colour, knockout holes, screen printing (plastic or steel screen available) and accessories. Certified to UL, RoHS and EU CE.

Applications
Industrial Electrical Wiring
IP67 protection with bolt-fix sealing suits factory distribution panel branch wiring and machine electrical entry protection; flame-retardant material extends service life.
Outdoor Control Enclosures
Triple protection - waterproof, dustproof, corrosion-resistant - ideal for street lighting controls, EV charging stations and outdoor automation equipment in long-term exposed environments.
PCB & Device Protection
Built-in PCB mounting screw holes allow direct circuit board installation for real-time status monitoring, revealing hidden risks - well-suited for industrial IoT devices.
FAQ
Q1｜What does IP67 mean for the WBX enclosure, and which environments is it suitable for?
IP67 means the enclosure is fully dust-tight (level 6) and can withstand immersion in 1 metre of water for 30 minutes (level 7). This makes it suitable for outdoor control boxes, machine tools, chemical plants and food processing equipment where moisture or water spray is present. For applications requiring continuous submersion, please enquire about IP68 upgrade options.
Q2｜How do I choose between PC, ABS and flame-retardant material?
PC (polycarbonate) offers superior impact resistance and is optionally transparent, making it ideal for high-strength applications or where a see-through lid is needed. ABS provides excellent dimensional accuracy at a lower cost, suitable for standard industrial use. Flame-retardant material is designed for environments with fire safety compliance requirements. For chemical corrosion or outdoor UV exposure, UV-stabilised grades are available - contact our sales team for guidance.
Q3｜Can knockout positions and hole sizes be customised?
Yes. WBX supports custom knockout positions and diameters to match any cable entry or mounting requirement. Screen printing (plastic or steel screen available) is also offered for branding logos or circuit identification labels directly on the enclosure body. Please provide a dimension drawing with your enquiry for a quotation.
Q4｜How does the bolt-fix design maintain IP67 sealing?
The mating faces of the base and lid are fitted with a waterproof gasket. Uniform tightening of all fixing bolts ensures the IP67 seal is maintained. Avoid uneven torque that could create gaps, and periodically inspect the gasket for ageing or deformation - replace as needed to preserve waterproofing performance.
Q5｜What international certifications does the WBX hold, and why does it matter for procurement?
The WBX is certified to UL (North American safety standard), RoHS (EU restriction of hazardous substances) and CE (EU market compliance). UL certification facilitates export to the US and Canadian markets; RoHS and CE are mandatory for the EU market and are key criteria when high-end B2B buyers evaluate supplier qualification.
