UNI7500H Hold Open Door Closer with Unitrol Arm (Parallel Arm Only) by Norton

The Norton 7500 Series Door Closer offers customers the ideal combination of superior perfomance, strength and quality. Ideal for interior or exterior doors in facilities that deman reliability. The series are certified to ANSI/BHMA A156.4, Grade 1.

Closers for interior and exterior doors shall be full rack-and-pinion type with cast aluminum alloy body. Closers shall be surface mounted and shall project no more that 2-3/16" (55mm) from the surface of the door. Closers shall be non-handed to permit installation on doors of either hand. Closer fluid shall contain lubricity and anti-oxidation agents. Closer fluid shall maintain stable viscosity to allow door closer to perform in temperatures ranging from extremely high to as low as -40°F. Closers shall have multi-size spring power adjustment to permit setting of spring from size 1 through size 6. Closers shall have two non-critical valves, hex key adjusted, to independently regulate sweep speed and latch speed. Closers shall have backcheck cushioning controlled by a hex key adjusted valve. Closers shall have backcheck position controlled by a hex key adjusted valve.

The 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 lbf. 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.

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-Degree door swing can be achieved when door, frame, hardware and arm function do not limit door swing.

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.

Sweep Speed Control Valve: Allows adjustments of door speed from the door's full position down to approximately 10-degrees from the closed position.

Latch Speed Control Valve: Allows adjustments of door speed from approximately 10-degrees 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-degrees of door opening. It slows/cushions the door opening, when the door is forcibly opened beyond its pre-adjusted opening speed 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 20º farther (approximately 95º).

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

Closer Fluid: NorGlide® closer fluid is a specially formulated multi-viscousity 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 temperature ranging from extremely high to as low as -40° F.

Hold Open Feature (Optional): Range of 90-180 degrees based on template location and mechanical adjustment.
