Manufactured by Milcor, the UL-SKY heat and smoke vents have polycarbonate Lexan covers that admit natural light. The vents open instantly when a UL-listed or FM-approved fusible link is exposed to a temperature of 165°F and automatically lock fully open. The vents are available with either an aluminum curb for ease in handling or a standard galvanized steel curb in widths from 4-6 feet and lengths of 4-8 feet, in 1-foot increments.
