Your impactable breakaway cold storage door! 

The Breakfree 400 door is a cold storage impactable door that offers the high insulation value of a 4″ thick (R-32) polyurethane door and the ability to break away upon impact.

This Breakfree 400 cooler door is designed to release the bottom section upon impact, either outward or inward, and to easily set the section right back into place. The 4″ thick expanded polystyrene (EPS) insulated knockout bottom section, in 30″ or 48″ heights, is made of an extremely resistant thermoplastic composite skin that can withstand heavy impacts.

The Breakfree™ 400 door is ideal for applications such as:

  • Cold storage warehouse
  • Grocery distribution center
  • Food processing plant
  • Pharmaceutical warehouse
