Norton UNI1601 Aluminum Storefront Door Closer, w/ Unitrol Arm

Norton UNI1601 Aluminum Storefront Door Closer, w/ Unitrol Arm

Unitrol Arm
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 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.

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

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.

Multi-Sized Door Closer: 1601
Adjustable through the power range of sizes 1 through 6 to comply with the opening force requirements as outlined in
the Americans with Disabilities Act (A.D.A.) and ANSI A117.1 for interior doors. Outlined in ANSI specification A156.4.
