When working in trenches, safety is non-negotiable—and trench boxes play a critical role in protecting your crew. But should you use an enclosed or open trench box? Here’s a quick breakdown to help you decide:

🔒 Enclosed Trench Boxes

What they are: Four-sided boxes with full containment, including end panels.

Pros:

  • Maximum protection against cave-ins

  • Better for deep trenches or hazardous materials

  • Meets stricter safety requirements

Best for:
Deep excavations, confined spaces, hazardous sites

Consider: Heavier and less accessible for crews or equipment

🧱 Open Trench Boxes

What they are: U-shaped or three-sided boxes without end panels.

Pros:

  • Easier access for workers and equipment

  • Lighter and easier to move

  • Ideal for quick or shallow jobs

Best for:
Shallow trenches, frequent access needs, utility work

Consider: Less protection on open ends

Which Should You Choose?

  • Need full protection? Go enclosed.

  • Need flexibility and speed? Open may be the way.
