1.01 WORK INCLUDED
The opening will be equipped with Wayne-Dalton rolling doors, Model as manufactured by Wayne-Dalton Corp.

1.02 RELATED WORK
Opening preparation, miscellaneous or structural metal work, access panels, finish or field painting, field electrical wiring, wire, conduit, fuses, and disconnect switches are in the Scope of Work of other divisions or trades.

2.01 CURTAIN
Curtain will be composed of interlocking standard gauge for door size, [(2 inch)(3 inch)] [(curved)(flat)] slats, roll-formed from galvanized steel (stainless steel) (aluminum) per ASTM standards and designed to withstand a 20 PSF windload. Ends of alternate slats will be fitted with metal windlocks. Bottom Bar will consist of 2 equal (steel) (stainless steel) (aluminum) angles, minimum 1/8" thick, to stiffen curtain with neoprene loop astragal. When required for additional security, provide (slide bolts) (cylinder locks) on the bottom bar operable from (coil side) (opposite coil side) (both sides).

2.02 GUIDES
Guides will be of roll-formed steel channels and angles or structural angles of (steel) (stainless steel) (aluminum) to form a slot of sufficient depth to retain curtains in guides to resist 20 PSF windload. Guides will be provided with integral windlock bars and bottom bar stops. Top of guide will be flared to reduce drag and wear.

2.03 BRACKETS
Brackets will be of steel plates, minimum 3/16", with permanently sealed ball bearings. Designed to enclose ends of coil and provide support for counterbalance pipe at each end.

2.04 COUNTERBALANCE
Curtain to be coiled on a pipe of sufficient size to carry door load with deflection not to exceed .03 inches per foot of door span and to be evenly balanced by helical springs, oil tempered torsion type designed with a 25% safety factor. Cast iron barrel plugs will be used to anchor springs to tension shaft and pipe.

2.05 HOOD
Hood will be minimum 24 gauge galvanized prime painted sheet metal, flanged at top for attachment to header and rolled at bottom to provide longitudinal stiffness. Hood will enclose curtain coil and counterbalance mechanism.

2.06 FINISH
Shop coat of rust inhibitive primer on galvanized and non-galvanized surfaces and operating mechanisms. Guides and bracket plates will be coated with a flat black prime paint. Aluminum finish to be (mill) (204R1 clear anodized) (bronze anodized). Stainless steel finish to be (mill)(#4).

2.07 OPERATION
Door will be operated by means of (manual push-up) (chain hoist ) (awning crank) (wall crank box) (motor operation), depending on desired effort needed to open door.

2.08 WEATHERSTRIPPING
Air-bar/Extr-Tite doors will include bottom astragal, exterior surface guide weatherstrip, and internal hood baffle weatherstrip.

2.09 LOCKING
(Manual push-up doors will have interior slide-bolts suitable for padlocks by others). (Chain-hoist door will have chain keepers suitable for padlocks by others). (Electric-motor operation doors will lock through the operator gearing). Slide bolts and cylinder locks can be provided other than standard.

CAUTION:
When specifying slide bolts or cylinder locks on electric-motor operated doors, electric interlocks required to prevent operation when lock bolts are engaged in the guides.
