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, multiviscosity 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
|
|
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 non-critical 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 preadjusted speed limitation.
|
Adjusta 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 nonhold open installations.
|
Sex Nuts/Sleeve Nuts (SN)
SN are for use on unreinforced hollow metal doors or to prevent any hollow metal door from collapse/dimpling. They can also be used for through-bolting on wood doors. SN are supplied for 1-3/4" (44mm) thick doors unless specified for 1-3/8" (35mm) or 2-1/4" (57mm) thick doors.
Thru Bolts & Grommet Nuts (TBGN)
TBGN are an alternative to SN for wood doors. TBGN are supplied standard for 1-3/4" (44mm) thick doors. They can be specified for 1-3/8" (35mm) and 2-1/4" (57mm) thick doors.
Spring Sizing Chart
|
Recommended
|
NOTE: Door closing force is not adjustable. Correct size must be selected.
All dimensions are for reference only and are in inches (mm) unless otherwise noted. Door sizing information is based on installation on standard weight doors, 7'0" (213cm) high x 1-3/4" (44mm) thick; hung on antifriction hinges and operating under normal conditions. Doors in excess of 7'8" (234cm) high or 1-3/4" (44mm) thick, templated openings beyond 150° or doors subject to wind or draft conditions will generally require the next larger size closer.
