Product Description
7904H-690-LH Norton 7900 Series Hold Open Overhead Concealed Closers with Spring Size 4 in Statuary Bronze Finish
The Norton 7904H-690-LH Overhead concealed closers are ideal for situations where a closer is needed, but concealment in the frame header is required or desired. The 7900 overhead closers are best suited for high-profile applications such as office buildings or conference centers. If 7900 series installed, only the solid one-piece arm is visible when the door is open; therefore, this unit provides a high degree of vandal resistance. When the door is closed, the closer, arm and slide track are fully concealed. This series are certified to ANSI/BHMA, Grade 1.
