The 9300BC is a light commercial door closer designed for exterior and interior doors such as condominiums apartments, motels or hotels. The closer is tri-packed for regular arm, top jamb and parallel arm installations Features Include: - 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: 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. - Non-Critical Control Valves: All control valves for sweep speed, latch speed and backcheck cushioning are noncritical and are adjusted by a standard 1/8" (3mm) hex wrench. - 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 speed limitation. - Finishes: All door closers are painted in waterborne acrylics. All steel parts, mounting plates and brackets are powder coated. The closers will withstand 100 hours of salt spray. ANSI requires 25 hours.
