Fasteners
All closers, with standard non-hold open and hold open arms are shipped with self-drilling, self-tapping and machine screws. Sleeve nuts (SN) may be ordered as an option.
• PR, CLP, CPS, UNI arms and slide tracks are shipped standard with sleeve nuts (SN) and self-drilling screws.
• Sleeve nuts (SN) are available for all closers and should be used on steel doors to prevent dimpling, or where proper door reinforcement has not been provided.
• Through-bolts and grommet nuts (TBGN) are another fastener alternative for wood doors. Specify door thickness 1-3/4" (44mm) or 1-3/8" (35mm) when ordering.
• Lobular Torx® drive screws, for tamper resistance, standard with 7570 and 7770 closers. Available as a special order for all other series closers.

Aluminum Alloy Housing
Closer bodies are constructed of a special aluminum alloy, carefully selected to accommodate 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 series 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. This permits the closer to be positioned on either right or left hand doors for most applications. Some options will require that the
hand of the closer be specified.

Sweep Speed Control Valve
Allows adjustment of door speed from the doors 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
Is 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 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.
