Rack & Pinion Operation: Provides a smooth constant control of the door through its full opening and closing cycle. 180-Degree door swing can be achieved when door, frame, hardware and arm function do not limit door swing.
Non-handed: 9300BC closers are non-handed and can be installed on either right- or left-hand swing doors. Pinion shafts extend vertically through the closer body in both directions.
Aluminum Alloy Housing: Closer bodies are constructed of a special aluminum alloy, carefully selected to accommodate interactive steel components and operating conditions.
Adjustable Backcheck Cushion Valve: Provides control of the door in the opening cycle, beginning at approximately 75-degrees of door opening. It slows/cushions the door opening, when the door is forcibly opened beyond its pre-adjusted opening speed limits.
Non-Critcal Control Valves: All control valves for sweep speed, latch speed and backcheck cushioning are non-critical and are adjusted by a standard 1/8" (3mm) hex wrench.
Adjust Power Shoe: Supplied as standard for a 15% (7-1/2%) power adjustment by relocating the forearm at the shoe, for regular arm and top jamb non-hold open installations.
