Norton CPS8301T Multi-Sized Architectural Thumbturn Hold Open Door Closer, w/ CloserPlus Spring Parallel Arm

Norton CPS8301T Multi-Sized Architectural Thumbturn Hold Open Door Closer, w/ CloserPlus Spring Parallel Arm

CloserPlus® Arm
Similar to the Parallel Rigid arm, this arm incorporates a stop at the arm’s soffit plate to dead stop the door
at a predetermined degree of door swing between 85° to 110°, in 5° increments. Prior to dead stop the door
closer’s backcheck feature slows the door speed to reduce the impact of the stop action.

The CloserPlus Arm is intended for use where an auxiliary door stop cannot be utilized and no more than moderate abuse is anticipated. Where more extreme conditions are expected, use of a Unitrol arm is recommended.

CloserPlus Spring™
This arm has all the characteristics of the CloserPlus arm with an additional steel buffer spring that provides greater
protection at the end of the door opening cycle.

For extreme conditions, use of a Unitrol arm is recommended. Available with or without hold open.

EXPLANATION OF FEATURES

Aluminum Alloy Housing
Closer bodies are constructed of a special aluminum alloy, carefully selected to accommodate interactive 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 interfere.

Non-handed
With few exceptions all series 8301/ 8501 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
will require that the hand of the closer be specified.

Non-Hold Open
Self-closes door every time door is opened. Auxiliary stop (by others)
required except when using the CloserPlus®, CloserPlus Spring™ or Unitrol® arms

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.

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

Standard Molded Covers
Molded of high-impact U.L. listed material. These covers are nonhanded for all applications.

Warranty
Limited 30-year warranty for defects and life of the building on the aluminum housing.

Closer Fluid
NorGlide® closer fluid is a specially formulated multi-viscosity 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 brass components, while maintaining stable viscosity to allow the door closer to perform in
temperatures ranging from extremely high to as low as -40° F.
