Product Description

7900-689-LH Norton 7900 Series Non-Hold Open Overhead Concealed Closers with Multi-Sized Spring 1-6 in Aluminum Finish

The Norton 7900-689-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.
