Breakfree 400

Your unbeatable cold storage door! 

The Breakfree™ 400 door is the cold storage door that offers the high insulation value of a 4" thick polyurethane door and the ability to break away upon impact.

This patented door is designed to release the bottom section on impact, from the inside or the outside, and to be easily set right back into place. The 4" thick expanded polystyrene (EPS) insulated knockout bottom section, in 30" or 48" height, is made out of an extremely resistant thermoplastic composite skin that can withstand heavy impacts.
