Adjustable Fusible Link Louvers

• Recommended for use in rooms where ventilation is needed and at the same time isolating the room whenever fire is present.
• When louver is exposed to heat at 165°F, the fusible link trips and the spring loaded louver blades shut to form an air tight fire and smoke seal.
• WHI Listing Mark with a 60-90 Minutes Fire Rating is stamped on the frame of the louvers.
• Installation is easy.
• No need to drill holes for fasteners.
• All screws are mounted on the room side leaving the corridor side free of fasteners for security purposes.
• Fuses are replaceable.
