Norton - Closer 7500 SN 689 - Aluminum Sprayed Finish
The series 7500 door closers are designed to comply with requirements of the Americans with Disabilities Act (A.D.A.) and ANSI standard A117.1. All series 7500/7700 door closers are ANSI/BHMA A156.4 Grade 1 certified. All Norton series 7500/7700 closers with non-hold open arms are listed by Underwriters’ Laboratories for labeled fire doors. This includes compliance to UL10C and UBC-72 (1997) for 3-hour assemblies. The product is manufactured in an ISO 9001 facility. These closers are also listed by the New York City Materials and Equipment Acceptance Division.
- Aluminum Alloy Housing:Closer bodies are constructed of a special aluminum alloy, carefully selected to acommodate 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 7500 and 7700 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, as noted on pages 6-8, will require that the hand of the closer be specified.
- 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® Packing: 7500 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 slows/cushions the door opening, when the door is forcibly opened beyond its pre-adjusted 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 20° farther (approximately 95°).
- 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.
- Warranty:These closers carry a limited ten-year warranty against defect, 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 7500 Multi-Sized Door Closer:Adjustable through the entire power range of door closer sizes 1 through 6, as outlined in ANSI/BHMA standard A156.4.
- The series 7500 also conforms to the minimum opening force requirements of the Americans with Disabilities Act (A.D.A.) and ANSI/BHMA standard A117.1 for interior doors.
