FIRE VENT ELIMINATES COVERS
The Bilco Co. has modified the design of its acoustic automatic Type ACDSH fire vent, which has increased its sound-transmission class from 45 to 46. The new design eliminates the vent’s lower, downward opening covers to simplify operation and reduce overall cost. The vent is well-suited for large buildings and is available in multiple standard UL-listed and FM-approved sizes. (203) 934-6363; www.bilco.com
