1.02 RELATED WORK
Opening preparation, 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 composed of interlocking (22) (20) gauge, No. 17 slats, rolled from (galvanized, bonderized steel with grey, baked-on finish) (aluminum) (stainless steel). Curtains wider than 16' 0" composed of (20) (18) gauge, No. 14 slats, rolled from (galvanized, bonderized steel with grey, baked-on finish) (aluminum) (stainless steel). All curtains comply with ASTM standards and are designed to withstand 20 PSF windload. Ends of alternate slats to be fitted with metal windlocks. Perforation on the flat portion of Secur-Vent slat consists of 1/16" diameter holes located on 3/32" staggered centers offering 41% open area over the entire length of each slat.
Bottom Bar consists of two steel angles, minimum 1/8" thick. Loop astragal is included. For additional security provide (slide bolts) (cylinder locks) on bottom bar operable from (either/both coil sides).

2.02 GUIDES
Guides of roll-formed steel channels and angles (structural angles) form a slot of sufficient depth to retain curtain in guides under 20 PSF windload. (Steel) (Stainless steel) guides provided with integral windlock bars and bottom bar stops. (Aluminum guide brush-type weatherseal - insect seal can be provided). (Similar type brush seal can be provided under lintel to complete the insect seal around opening perimeter).

2.03 BRACKETS
Brackets 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. (Square brackets provided).

2.04 COUNTERBALANCE
Counterbalance of the upward-coiling curtain precisely balanced by helical springs, 25 pound maximum lift effort for push-up doors, oil tempered torsion type designed with 25% safety factor. Curtain is coiled on a pipe of sufficient size to carry door load with deflection not to exceed .03" per foot of door span. Cast iron barrel plugs used to anchor springs to tension shaft and pipe.

2.05 HOOD
Hood of #24 gauge galvanized steel, flanged at top for attachment to header and beaded at the bottom to provide longitudinal stiffness. Hood will enclose curtain coil and counterbalance mechanism. (Back hood can be provided whenever coil is exposed from opposite side). Hood coated with baked epoxy enamel primer to match curtain. Hood will conform to (round) (square) bracket.

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

2.07 OPERATION
Doors operated by means of (manual, push-up) (chain hoist) ((awning crank) - (bracket) (wall mounted)), or ((motorized, (bracket) (wall mounted)), depending on effort needed to open door.

2.08 LOCKING
(Manual, push-up doors have interior slide-bolts suitable for padlocks by others). (Chain-hoist door has chain keepers suitable for padlocks by others). (Electric-motor operation doors lock through the operator gearing). Non-Standard slide bolts and cylinder locks can be provided.

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