7900 SERIESOverhead ConcealedDoor Closers

7900 SERIESOVERHEAD CONCEALED DOOR CLOSERSOVERVIEWIntroductionOverhead concealed closers provide an aesthetically appealing way to close a door. In situations where a closer is needed butconcealment in the frame header is required or desired, the Norton 7900 closer is the ideal solution for door control. Once 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 thedoor is closed, the closer, arm and slide track are fully concealed. For applications where concealment is required and security is themain concern, the 7970 should be used.This heavy-duty, durable closer package includes a steel track, steel slider, polymer slider pads and dress plates. The steel track and slideroffer additional strength to the unit, while the polymer pads provide quiet operation and easy assembly. Standard features include rackand pinion operation, adjustable sweep and latch, and adjustable backcheck cushioning and positioning.The 7900 overhead closers are best suited for high-profile applications such as office buildings or conference centers. The 7970 securityclosers offer the necessary concealment and tamper resistance required in detention and psychiatric facilities. Used in conjunction with thedoor position switch (DPS) they provide the ability to monitor door status remotely.TABLE OF CONTENTSOverview & Features . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2-3How to Order . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4Door Size and Finishes . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 5 Features . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 6Optional Features . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7Suggested Specifications and Standards . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 8Technical Details . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 9-11Parts List . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 12-132Copyright 2001-2015, Yale Security Inc., an ASSA ABLOY Group company.
