LABELED COUNTER SHUTTERS
Atlas Door Labeled Counter Shutters are designed to provide
fire protection while still functioning as a standard counter shutter. Available in manual
push-up, awning crank, or motor-operated, These shutters are ideal for small opening
protection because of reduced clearance requirements and compact size of guides and hoods.
A governing device controls the shutter's rate of descent. The automatic closing mechanism
is activated by a fire alarm system, smoke or heat detector, or a melting fuse line 165°F
(74° C).
For new wall opening, an integral frame package can be
provided with UL class B label.
When the aesthetic of a labeled integral frame shutter is
desired for an existing wall opening, Atlas Door can provide a between jamb mounted
counter shutter with its sill & trim package.
When controlling smoke is a concern. Atlas Door can provide
a rated smoke shutter with UL-labeled brush weather stripping or vinyl stripping to
prevent the passage of smoke through the opening.

Street, Suite 1600, Cincinnati, Ohio 45202-4036.
2.02 Materials / Construction
A. Type: Atlas door Model (L##PS) Labeled
Counter Shutters curtain slat construction.
1. Slats:cold roll-formed in continuous
lengths of (gray) (tan)painted galvanized steel interlocked to form curtain.
B. Endlocks: each end of alternate slats
fitted with endlocks to act as a wearing surface in the guides to
maintain slat alignment and to prevent flame passage.
C. Gauge: thickness of slat material to
satisfy Underwriters' Laboratories requirements.
D. Galvanizing: zinc-coated in accordance
with ASTM A-653.
E. Bottom Bar: curtain reinforced with a
bottom bar with lift handles provided on both sides of shutters.
F. Astragal: bottom bar furnished with an
astragal to protect counter top finish.
