Model XSV-845

Steel Grille
8" Deep - Inverted V-Blade

The XSV-845 is a steel grille designed to FEMA 320 or FEMA 361 guidelines for shelters or safe rooms. It has been designed to withstand design loads from 260 PSF to 300 PSF produced by extreme wind phenomena such as tornadoes and hurricanes. The XSV-845 has been tested with impacts of 15lb 2" x 4"s traveling at 100 MPH per ICC 500. This makes the XSV-845 compliant for wind borne debris in all tornado or hurricane regions in the United States.
