Furnish Titan Aluminum Rolling Doors, series 500 as manufactured by “ADT” complete with curtain, hood, guides, counterbalance and options as specified.

Curtains consists of interlocking AT3 TITAN slats extruded aluminum type 6061-63. Designed to offer a flush appearance on both sides. Auto locking feature causes the curtain to resist opening when force is applied from under the bottom bar. Tubular construction minimizes bilateral deflection. Wall thickness is (.055″) 16 gauge per side. Each end of alternate slats are to be assembled with end locks to maintain slat alignment and to act as a wearing surface inside the guides. Slats are designed to withstand windloads of a 20 psf.

Bottom bar to be extruded aluminum type 6061-63. Designed specifically for the TITAN SERIES Bottom bar shall have a rubber astragal to form a weather tight seal upon closing of service door.

Spring counterbalance is to be housed in a steel pipe of the appropriate diameter and wall thickness as to support curtain. Deflection shall be limited to a maximum of .03″ per ft. of door width. Springs are to consist of helical torsion type designed to meet a 25% safety load factor. Safety factor allows for safe operation, ease of use, and longer spring life. Springs are to be grease packed and anchored, using a cast iron anchor, to a cold rolled steel inner shaft. Spring tension shall be fully adjustable from outside of end bracket plate. To insure smooth operation end bracket plates shall contain sealed ball bearings to minimize wear of pipe shaft.

End bracket plates shall consist of steel plate no less than 3/16″ thick. Bracket plates are to house pipe shaft and counterbalance assembly. Shaft is attached to plate by sealed ball bearings fitted onto plate.

Pocket Seal Guides shall consist of extruded aluminum of adequate depth to provide for proper slat penetration and windloading. Guides to be fitted with nylon brush pile on inner walls. This sandwiches the curtain on both surfaces forming a seal between the curtain and guide, prohibiting airflow through the guides.

Hoods shall consist of a minimum of #24 U.S. gauge steel. Hoods are designed to protect and house counterbalance assembly.
Full weather stripping shall include

• Neoprene hood baffle
• Nylon pile on all ends of guides
• Neoprene astragal attached to bottom bar

Locking for chain operated doors to be slidebolts mounted on bottom bar with provisions for padlocks. Gearing within motors to be self locking.
