Caution:

• Door Closers for Low Opening Force Applications:

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 nonhanded 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.

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 opening speed limits.

Warranty:

• These closers carry a limited 25-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.
