Select The Appropriate Waterproof Junction Box With Suitable Wall Thickness.

A wall thickness of waterproof plug box that is too thin is prone to deformation during installation, handling, or vibration. A wall thickness of water tight electrical box that is too thick may unnecessarily increase the overall size and weight, affecting wiring and the utilization of space within the box.

The wall thickness of waterproof cable box is typically determined by referring to industry standards and the actual usage environment. For general household or light-load applications, the wall thickness of plastic weatherproof electrical box is controlled between approximately 1.5 mm and 3 mm, balancing strength and economy. For higher loads or more complex environments (such as outdoor, humid, or high-vibration conditions), a thicker structure will provide more stable mechanical support and sealing.
