The SG-8VP is a heavy-duty yet architecturally pleasing grille that features a secondary steel barrier screen to protect speakers from damage in applications where vandalism and abuse are a concern. It is ideal for installation in schools, hospitals, manufacturing and distribution centers, transportation terminals, detention centers and correctional facilities. This rugged grille is 14.438” square and formed from 14-gauge steel to withstand damage and abuse. It’s engineered with a 22-gauge steel barrier screen (painted black) and open chipboard gasket both of which, are placed between the grille and the speaker cone to prevent damage from pointed objects.
