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

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.

Carbon Steel plate not less than 1/4” thick with ball bearings at rotating support point on drive side bracket.  When bolted to the wall, the mounting angle 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

Alpine’s 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. 

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 are designed to prevent wear on the shaft at each end of the pipe/barrel.
