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.

Tri-Style®
8301/8501 comes with screws, brackets and soffit plates to allow for regular, top
jamb, and parallel arm installations.

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.

DOOR CLOSER POWER OPTIONS

Series 8301/8501 Multi-Sized Door Closer

Adjustable through the power range of sizes 1 through 6; as outlined in ANSI/ BHMA specification A156.4 option PT 4H.

Closers will also comply with the opening force requirements as outlined in the Americans with
Disabilities Act (ADA) and ANSI/BHMA standard A117.1 for interior doors.

Adjustable Delayed Action Closing
An optional hydraulic feature that adds a third speed range to the closing cycle. This feature becomes
effective when the door is opened and released at any point beyond 70°. The amount of time delay depends
upon the combination of the angle of door release and valve adjustment. The valve can be adjusted with a 1/8"
(3mm) hex key from no delay time up to maximum delay times of:

Door Opened and Released at: 180° - Approximate Time of Delay Cycle: 4-5 minutes

Door Opened and Released at: 120° - Approximate Time of Delay Cycle: 2-3 minutes

Door Opened and Released at: 90°  - Approximate Time of Delay Cycle: 25-30 seconds

Pressure Relief Safety Valve
The delayed action hydraulic system contains a pressure relief valve. Any time the door is forced toward the
closed direction while it is in the closing cycle, the valve will open and permit the door to close. This prevents
damage to door, frame and closer.

Suggested Applications
Delayed Action closing allows slow moving traffic to clear the opening before the door closer’s normal
closing cycle begins. This feature can be helpful in health care facilities such as hospitals and nursing homes. It
provides sufficient time for persons on crutches or in wheelchairs to pass through a door without concern of
it closing. At the same time, it can accommodate the facility's staff with movement of food service carts, beds, and other wheeled traffic.

Use of delayed action closers on many doors throughout industrial and commercial buildings can also assist the flow of traffic. Locations where additional time to clear the opening is advantageous are doors between office and factory/warehouse facilities, doors to workshops or laboratories, to kitchen and food processing areas, etc.
