Let it Roll

The Extreme 300 Series MicroCoil Grille reduces headroom for rolling grilles by 50% while providing building safety. The door decreases angles through patented curved vertical links, reducing the number of voids and headroom required and tightening coils in the process. Meeting ADA Standards for Accessible Design, the door is wind loaded and can withstand up to 20 psf static design pressure standard—up to 40 psf optional.
