A PVC junction box is a wiring essential built to outlast moisture and corrosion. It’s lightweight, 绝缘 (insulating), and perfect for damp or humid spaces. Lemotech crafts these boxes to excel. See the image below.

Key Traits of a PVC Junction Box
Lemotech’s boxes use high-grade PVC, a material that resists rust, rot, and chemicals. It handles temperature swings from -20°F to 140°F without cracking. Smooth interiors protect wires from nicks, keeping connections secure.
Where PVC Junction Boxes Shine
Wet Areas
Bathrooms, kitchens, and laundry rooms rely on them. They shield wire joints from steam and water splashes, avoiding shorts.
Outdoor Setups
Mounted under eaves or near sprinklers, they stand up to rain and dew. Ideal for garden lights or pool pump wiring.
Industrial Zones
Factories with chemical exposure use them. PVC won’t react to cleaners or solvents, ensuring long-term safety.
