Counter Fire Shutters are designed specifically for pass-thru openings requiring fire protection. These units, with clean-line styling and compact dimensions, are proportioned for small counter openings. U.L. 3-hour labels are affixed to all units, for installation on interior fire walls. In case of fire, the fusible link releases the mechanism and the curtain descends automatically. Normally, the unit is used as a push-up operated counter shutter.
