FEATURES
Tri-Style Installation: Versatile closer
packaged for regular arm, top jamb or parallel arm installation.
Non-Handed: Pinion shaft extends
vertically through the closer body in both directions. This permits the closer to be
installed on either right or left hand doors for all applications. A cap conceals the
closer shaft not in use.
Aluminum Alloy Shell: Norton closer shells
are constructed of a special aluminum alloy, carefully selected to accommodate individual
closer characteristics and operating conditions.
Rack & Pinion Operation: Provides a
smooth transmission of power, for control of the door through its full opening and closing
cycle.
Adjustable Sweep Speed: An independent
regulating valve, hex-key-operated, permits adjustment of the general closing speed.
Adjustable Latch Speed: An independent
regulating valve, hex-key-operated, permits adjustment of the door's speed for
approximately the last 10° of the closing cycle.
Adjustable Backcheck Cushioning: Available
as an option, an independent regulating valve, hex-key-operated, provides an adjustable
hydraulic cushion to the door opening speed toward the end of the opening cycle.
Order Series 1600BC.
Non-Critical Valves: All control valves
for sweep speed, latch speed and backcheck cushioning or delayed action closing are
non-critical and are adjusted by a standard 1/8" hex-key.
"Goof-Proof" Main-Arm Broach: The
configuration and marking of the main-arm broach help to assure positive alignment of the
arm for each type of closer installation.
Corrosion Resistant Closer: The shell,
pinion bushing assembly and caps of this closer are aluminum alloy materials. All other
exposed components are of stainless steel, or zinc alloy materials to provide excellent
resistance to corrosive environments. For standard non-hold-open applications only.
