This also makes it beneficial in vandalism-prone areas. It is on the push side of the door and the arm assembly extends almost parallel to the door. In the closed position, there is very little or no hardware projecting beyond the frame face in most situations. Due to the geometry of the arm it is approximately 25% less power efficient than a regular arm application. The entire closer and arm assembly are mounted below the frame stop. Top rail clearance dimensions will vary based on the type of cover used. (See pg.15) Non-Hold Open Self-closes door every time door is opened. Auxiliary stop (by others) required.

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 8300/8500 and series 8301/8501 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 6-7, 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 Valve Allows adjustment of door speed from approximately 10° down to the door’s fully closed position. Tri-Style® 8301/8501 comes with screws, brackets and soffit plates to allow for regular, top jamb, and parallel arm installations. Adjustable Backcheck Valve Provides control of the door in the opening cycle, beginning at approximately 75° of door opening. It cushions the door opening when the door is forcibly opened beyond its pre-adjusted limits. Standard Molded Covers Molded of high-impact U.L. listed material. These covers are non-handed for all applications. Warranty Limited 25-year warranty for defects 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 8300/8500 Sized Door Closer Available in five different power sizes (2, 3, 4, 5 or 6). Each power size is adjustable up to 50% stronger than the minimum closing force for that size; as outlined in ANSI/BHMA standard A156.4 option PT 4C. Closers will also comply with the opening force requirements as outlined in the Americans with Disabilities Act (ADA) and ANSI/BHMA standard A117.1 for interior doors.
