| Specifications | 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. 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.
