Norton 1604BCH Size 4 Aluminum Storefront Hold Open Door Closer, Regular Arm

Norton 1604BCH Size 4 Aluminum Storefront Hold Open Door Closer, Regular Arm

Regular Arm
This is the only pull-side application where a double lever arm is used. It is the most power-efficient application for a door closer. Sufficient frame, door and/or ceiling clearance must be considered.
Since the arm assembly projects directly out from the frame, this application may present an aesthetics issue or be prone to vandalism.

Top Jamb
For efficiency reasons this application provides the best alternative to the regular arm application. There must be sufficient frame face and/or ceiling clearance for this application. It requires a top rail on the door of just 2-1/8" (54mm). This application provides the best door control for doors in exterior walls that swing out of a building.
The entire door closer and arm assembly project from the frame, similar to the regular arm application, where the matters of appearance and malicious abuse can be of concern. Consideration must be given to depth of the frame reveal.

Parallel Arm
This application provides the most appealing design appearance for a surface-mounted door closer having a double lever arm. This may also be beneficial in vandalism-prone areas. It is on the push side of the door and the arm assembly extends almost parallel to the door. In the closed position, there is very little or no hardware projecting beyond the frame face in most situations.

Due to the geometry of the arm it is approximately 25% less powerefficient than a regular arm application.

The entire closer and arm assembly are mounted below the frame stop, requiring a top rail clearance on the door of between 5-3/8" (137mm), when using a low-profile arm (1680 series), to 6-3/8" (162mm), when

EXPLANATION OF FEATURES

Aluminum Alloy Housing
Closer bodies are constructed of a special aluminum alloy, carefully selected to
accommodate interaction with steel components and operating conditions.

Rack & Pinion Operation
Provides a smooth constant control of the door through its full opening and closing cycle. 180°
door swing can be achieved when door, frame, hardware and arm function do not limit door swing.

Non-Handed
With few exceptions, all series 1600BC and series 1601 door closers are non-handed and can be installed on either right- or
left- hand swing doors. Pinion shaft extends vertically through the closer body in both directions. Some options (such as Parallel
Rigid hold open arms) will require that the hand of the closer be specified.

Tri-Style®
1600BC/1601 closers come with screws, brackets & soffit plate to allow for regular, top jamb, &
parallel arm installations.

Sweep Speed Control Valve
Allows adjustment of door speed from the door's full open position down to approximately 10° from the closed position.

Latch Speed Control Value
Allows adjustment of door speed from approximately 10° down to the door’s fully closed position.

Hold Open
Achieved by means of friction or ball and detent/roller. Friction hold open has a range of 90° to 180° using template
location and mechanical adjustment. Ball and detent or roller hold open is effective in a range of 85° to 110°.
Hold open arm door closers are not permitted to be used on fire door assemblies.

Adjustable Backcheck Cushion Valve
Provides control of the door in the opening cycle, beginning at approximately 75° of door
opening. It slows/cushions the door opening, when the door is forcibly opened beyond its preadjusted opening speed limits.

Warranty
These closers carry a limited 30-year warranty against defects and a limited lifetime warranty on the aluminum housing.

Closer Fluid
NorGlide® door closer fluid is a specially formulated hydraulic fluid that contains lubricity and
anti oxidation agents that provide optimum performance and efficiency. This fluid complements the interaction of the door

closer's aluminum housing with its steel and zinc components, while maintaining stable viscosity to allow the door closer to

perform in temperatures ranging from extremely high to as low as -40° F.
