Norton UNI7500 Door Closer w/ CloserPlus Spring Parallel Arm

Norton CPS7500 Door Closer w/ CloserPlus Spring Parallel Arm

Unitrol® Arm
Can be used for either parallel arm or top jamb applications. Unitrol arms combine the features of a double lever
arm overhead door stop/holder with the backcheck feature of the door closer to reduce door stopping shock loads
to a minimum. The Unitrol uses a compression spring buffer at the soffit plate/arm shoe that will absorb 30 lbs. of
force, 5° prior to the door’s dead stop. Coupled with the door closer’s backcheck feature, this arm provides the most
controlled stop available with a surface door closer.

For parallel arm applications there are three different length arm assemblies. Each length is designed for a specific range of
door widths to provide precise door control. This further lessens the dead stop impact on the door’s hinges/pivots

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 7500 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.

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 slows/cushions the door opening, when the door is forcibly opened beyond its pre-adjusted limits.

Adjustable Backcheck Position Valve
Allows the door opening position, where backcheck cushioning begins, to be adjusted to a greater door
angle, up to a maximum of 20° farther (approximately 95°).

Non-Hold Open
Self-closes door every time door is opened.

Standard Molded Cover
Molded of high-impact U.L. listed material and covers the entire closer body assembly. This cover is nonhanded for all applications.

Warranty
These closers carry a limited 30-year warranty against defect, 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.

DOOR CLOSER POWER OPTIONS

Series 7500 Multi-Sized Door Closer
Adjustable through the entire power range of door closer sizes 1 through 6, as outlined in ANSI/BHMA standard A156.4.
The series 7500 also conforms to the minimum opening force requirements of the Americans with Disabilities Act
(A.D.A.) and ANSI/BHMA standard A117.1 for interior doors.

Extra Power
For applications that require additional closing power to overcome stack pressure, high wind, unbalanced HVAC
and other issues that can prevent the doors from closing, model 7706EP is available.
