JUNCTION BOX
Company & Coverage
Product Summary
Our Junction Box product line is designed for industrial, commercial and outdoor electrical installations. Built from robust materials (such as CRCA steel, stainless steel, die-cast aluminium, or UV-stable plastic/ABS), our junction boxes provide secure, dust-tight, water-tight enclosures for terminating cables, protecting wiring junctions, and housing terminal blocks. They are available in standard sizes and custom configurations to meet project-specific needs: wall-mount or pole-mount; indoor or outdoor; IP-rated for harsh environments; with single- or multiple-entry knockouts; with optional cable-gland plates. Whether you need small “instrument junction boxes” or large distribution enclosures, National Pole offers the product, finished and ready for installation.
Performance Features
Our junction boxes incorporate the following features:
- Material options: High-quality CRCA steel sheet (1.6 mm & above) for welded construction, stainless steel (SS 304 / SS 316) for corrosive / outdoor conditions, aluminium or GRP/FRP for specialized use.
- Surface treatments: For steel-based boxes — chemically pre-treated, powder-coated or epoxy/polyester finish; for aluminium/die-cast — corrosion-resistant coating; plastic versions include UV-stabilised ABS/PC with gasketed covers.
- Protection class: Enclosures designed for high ingress protection ratings (e.g., IP55, IP65, IP66) to suit indoor/outdoor applications and harsh environments (dust, moisture, chemical exposure) as referenced.
- Cable-entry flexibility: Knockouts, cable-gland plates, gland glands supplied or pre-machined; multiple orientations for side/bottom entry.
- Mounting options: Wall mounting, pole bracket, floor mounting; back-plate for terminals; hinged doors or removable covers for easy access.
- Custom sizing & configuration: Standard size ranges offered but custom dimensions available to meet site-specific wiring, instrument or control-panel needs.
