Standard Features
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		All door closers are supplied with a temperature stable, multi-viscosity fluid. This fluid will permit the door closer to perform within a wide temperature range from very high to as low as -40°F.
Non-Handed		With few exceptions all series 3301/3501 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.
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-Packed		3301/3501 come 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. Standard covers are non-handed for all applications.
Warranty		Limited ten-year warranty for defects and life of the building on the aluminum housing.

Sex Nuts furnished standard with the Holder/Stop arm.
