How does the Ember Deflector System™ work?
The patent-pending Ember Deflector System™ is made from high quality stainless steel that can withstand temperatures up to 2750 degrees, far exceeding the normal temperatures of fires. Its simple design allows you to slide the doors over your vents, thereby closing them off when fire danger is imminent. The doors slide open just as easily after the fire danger has passed, allowing the important task of ventilating your attic and crawlspace to continue.
