7900 GENERAL INFORMATION
Norton® Series 7900 Concealed
Closers are concealed in the transom of the door frame. The slide track and hold-open
mechanism are concealed in the top rail of the door. Since only the solid one piece arm is
visible when the door is open, this unit provides a high degree of tamper resistance. With
the door closed, the unit is tamper proof because the closer, arm and slide track are
fully concealed. This configuration allows the architect to maintain door and frame
contours without sacrificing door control.
This closer offers a complete range of separate control
adjustments...sweep speed, latch speed, backcheck positioning, backcheck cushioning and
spring power. The slide track and arm provide a shock absorbing action to bring the door
to a controlled stop.
Series 7900 Closers can be the answer where it is desired
to provide door control that is completely concealed. It is an ideal door closer for
applications where concealment of door hardware is an important consideration.
