 SLIDE TRACK CLOSERS PUSH (HINGE)
SIDE MOUNT
Norton Series 8300ST/8500ST Slide Track Door Closers
combine the door control of the Series 8300/8500 closer with the subtle appearance of a
slide track and arm. Since the arm does not project, the overall installation exhibits a
smooth uncluttered appearance.
The closer body is surface mounted to the hinge (pull) side
of the door's top rail with the slide track fastened to the frame face. They present an
unobtrusive narrow profile installation. Also, since there is no hardware projecting when
the door is closed, it provides a deterrent to vandalism.
Series 8300ST/8500ST Closers are nonhanded. They feature
50% spring power adjustment, sweep speed, latch speed and backcheck cushioning control
valve adjustment. The Series 8300ST is supplied with a molded Slim Style cover: Series
8500ST is supplied with a molded Full Cover.
These door closers are available for either non-hold-open
or hold-open operation. For doors requiring a maximum swing and/or hold-open of 100° or
less, the track has a spring cushion assembly to assist in bringing the door to a
controlled dead stop. The hold-open track assembly also has an engage/disengage hold-open
feature, and hold-open tension adjustment. The ranges of door swing and the range of
hold-open are as follows:
Non-Hold-Open
85° to 110° with Spring Cushion Track
85° to 180° without Spring Cushion Track
Hold-Open 85° to 110°
A telescoping arm assembly permits adjustment of door swing
and/or hold-open point in 3° increments within the ranges listed.
