8501ST Door Closer with Slide Track Single Lever Arm (Pull Side Standard) by Norton

The 8000 Series Door Closers offer the ideal combination of appearance, reliability and durability in today's market. With features such as staked valves, precise valve adjustment and a complete range of arm and cover options, this closer can meet virtually any application challenge.

The Norton 8501 Series Closers for interior and exterior doors shall be full rack-and-pinion type with cast aluminum alloy shell. Closers shall be surface mounted and shall project no more than 2-1/8" from the surface of the door. Closers shall be non-handed to permit installation on doors of either hand. Closer fluid shall contain lubicity and anti-oxidation agents. Closer fluid shall maintain stable viscosity to allow door closer to perform in tempatures 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 and latch speed. Closers shall have adjustable backcheck intensity controlled by a hex key adjusted valve.

Slide Track: Whether pull- or push-side mounted, slide track provides the designer with the smoothest lines available in a surface-mounted door closer. The single lever arm allows components to be located in a stack configuration to minimize projection and eliminate obtrusive arm angles. The arm geometry reduces door closer power efficiency by approximately 25% from that of a regular arm.

Door Closer Power Options:

8501: The 8501 Series is a Multi-Sized Door Closer that is adjustable through the power range of sizes 1 through 6.

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: 8501 closers are non-handed and can be installed on either right- or left-hand swing doors. Pinion shafts extend 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.
