GALVANIZED ENDLOCKS/WINDLOCKS
Ductile Cast iron, hot-dipped galvanized endlocks/windlocks are riveted to the ends of the slats with 1/4” rivets. Option in brass material which prevents sparking. Furnish windlocks based on wind load specifications. 

BOTTOM BAR
Two galvanized roll-formed steel or structural steel angles which are designed to reinforce the bottom of the curtain. Equipped with rubber astragal or a sensing edge which extends into the guides. Galvanized steel as per ASTM-A653/A653-M.
OPTION: Exo-Shield™ Powder coating to match curtain. 

BRACKETS
Carbon Steel plate not less than 1/4” thick with ball bearings at rotating support points on both brackets.  When bolted to the wall, the mounting angle that supports the barrel/pipe assembly and forms an end enclosure. OPTION: Stop lock bearing which prevents the door from free falling in the event of a drive operation failure.

GUIDES
Alpine’s Grey ExoShield™powder coated Guide system is designed using structural steel angles with a minimum thickness of 3/16” meeting the ASTM A36 Standard that are bolted together with ⅜” fasteners in 1-¼” slotted connections bolted at a minimum 24” on center. One inch spacing of the guide channel ensures smooth operation. Vinyl clip on guide weather seal is standard for the exterior with the option of adding seals on the interior

COUNTERBALANCE ASSEMBLY
Pipe shall be manufactured with a diameter and wall thickness to restrict maximum deflection to 0.03” per foot of door width.  Springs are helical torsion type which are designed to include an overload factor of 25% for optimum ease of operation., The springs are grease packed and mounted on a cold rolled steel inner shaft. Spring tension is adjustable from the outside of the end bracket. Sealed ball bearings as described above are designed to prevent wear on the shaft at the drive end of the pipe/barrel.
Life Cycle: 20,000 up to 400,000  

HOOD Hexagon (Option: Square or Round)
Made from #22-gauge galvanized steel as standard and formed to fit the contour of the end brackets.  Optional material in stainless steel or aluminum. Equipped with a neoprene air baffle.  Finish Options: #4 stainless steel or ExoShield powder coated to match curtain

LOCKING 
Option 1: Slide bolt locks on the bottom bar.
Option 2: Cylinder locks. (Electric interlocks are recommended for motorized doors to prevent damage.)
Option 3: Motor acts as lock.

HOT DIPPED GALVANIZING (OPTION)
Applied to the guides, brackets and gears in addition to Standard Specifications. Applied where conditions of extreme or unusual atmospheric contamination is present. As per ASTM-A123

(Pipe Shafts available with Zinc Enriched Powder Coating or Stainless-Steel)

FASCIA (OPTIONAL)
Useful where the area behind the hood is open, as seen in a between jambs type mounting configuration or other condition that exposes the opposite of coil side. Especially applicable with pre-engineered buildings. Finish is to match curtain.

Doors can be manual hand crank, hand chain or motor operated with a NEMA 1 Open/Close/Stop push button station. All operators can be adapted to specific conditions. 

Alpine Motor Operators

> View Access Control Details 

SAFETY ENTRAPMENT PROTECTION:
Option:
Photo Safety Sensors mounted to the guides 6” above the finished floor directing a beam across the opening which will stop the door and reverse to the fully open position if broken while door is cycling to close.
Option: Redi-Reverse Light Curtain consists of a 6’0” high light curtain integral to the guides, left and right. If an object passes through the light curtain during the close cycle, the door will reverse to the open cycle and come to rest upon reaching the open limit.
Option: NEMA 4X (weather resistant) photo safety sensors mounted to the guides 6” above the finished floor that project an infrared beam across the width of the door.  Breaking the beam while the door is in motion will result in the immediate stop of downward travel and reverse the door to reopen to the top limit.
Option: Electric Monitored Sensing edge with a coil cord or take up reel, or a wireless monitored transmitter and receiver type monitored sensing edge
