PART II - PRODUCTS

2.01 Manufacturer and Product Description

A. Acceptable product: Riviera Contract DustGuard 1" (25mm) blind manufactured by Levolor Home Fashions.

B. Materials:

Headrail shall be of .025" thick Tomized steel, "U" shaped, 1" high x 1-9/16" wide with flanged edges at top, and coated with baked-on finish. All hardware shall be enclosed in the metal headrail.
Guardian Tilter mechanism shall be of a not less than .042" thick Tomized steel housing with a self-lubricating nylon, automatically disengaging worm and gear mechanism to provide maximum closure, eliminate overdrive, and prevent strain or damage to blind.
Tilt Wand shall be transparent with a hexagonal cross section approximately 5/16" across flats.
Cord Lock shall be .042" thick Tomized steel and shall be securely attached to headrail. It shall be a crashproof type with sufficient sensitivity to lock slats at desired height upon release of cords.
Drum and cradle shall be provided for each ladder.
a. Drums shall be of .031" thick Tomized steel having two holes with rolled edges to anchor barbs of both ladder ends.
b. Cradles shall be of .042" thick Tomized steel having two holes with rolled edges to guide cords through bottom of headrail without abrasion. They shall provide bearing support for the tilt rod, thus preventing the weight of the blind from being transferred to the tilter. Cradles shall center drums over ladder openings.
Tilt rod shall be designed to achieve a torsional deflection limit of less than or equal to 6 degrees per 30" length with an applied torque of one foot-pound. A U-shaped tilt rod with a circular radius of approximately 0.125" is used for average blind sizes and lengths. For blinds over 60" wide and under 80" long, or over 55" wide and over 80" long, tilt rod shall be solid D-shaped with an average cross section of 0.28".
End Braces shall be of .037" thick Tomized steel with reinforcing ribs and field adjustable tabs. End braces shall incorporate a field adjustable tab to insure secure installation, center blind in window, and prevent lateral movement.
Installation Brackets shall be of a least .048" thick Tomized steel with baked-on finish to match headrail. The brackets shall incorporate a rivet-hinged safety locking front cover to permit removal of headrail without lateral movement. Mounting holes shall be located to accommodate overhead, side, or face mounting.
Intermediate Brackets shall be of .050" thick Tomized steel and shall be installed with blinds over 60" wide and under 80" long, or over 55" wide and over 80" long. Brackets shall be supplied as required.
Ladders (slat supports) shall be braided polyester yarn-dyed to Levolor color standard. The two vertical components shall be .076" x .038" designed for maximum flexibility combined with minimum stretch and tensile strength of not less than 50 lbs. per cable. Horizontal components (rungs) shall consist of not less than two cables inter-braided with the vertical components. Ladder shall support the slats without visible distortion. Distance between slats shall not exceed 19.6mm (nominally 15.7 slats per vertical foot). Distance between ladders shall not exceed 23" for blinds up to 80" long. For blinds over 80" long, distance between ladders shall not be greater than 22". Distance between end ladder and end of slat shall not exceed 7".
Slats shall be of 5000 series magnesium aluminum alloy only, which includes recycled aluminum materials. Aluminum alloy shall be tempered to optimize tensile and yield strength for superior slat strength, resiliency, and corrosion resistance. Slats shall be nominally 1" wide and .0055"+/- .0003 (prior to coating); after coating, the thickness of the slats shall be nominally .0060". Slats shall have a coating thickness of .8 mil to 1.5 mil. Slats shall perform to 500 hours of 100% relative humidity testing, 300 hours of 5% salt spray solution at 95 degree F testing, and 250 hours of accelerated weathering testing without blistering, fading, corroding, or adhesive failure. Slat thickness and ladder support distances shall prevent visible sag or bow after continued use indoors.

DustGuard feature is a permanent, patented paint process that disrupts the natural static attraction of airborne dust particles, reducing dust build-up by 50-70 percent. (NOTE: Certain Mark I finishes may not be available with the DustGuard feature. Please confirm selection with DustGuard color list.)
Bottomrail shall be of .031" thick Tomized steel formed after coating and shall be provided with color compatible molded plastic ladder and end caps having integral protrusions designed to prevent bottom bar from marring window sill and/or mullions. End caps shall provide hold-down capability designed to prevent bottom bar sway on doors or in windy exposures.
Lift Cord shall be braided of high strength, 1.4mm diameter polyester fiber with a high tenacity polyester core, 34 picks per inch, 16 carrier smooth braids, and shall be flexible, have minimum stretch, maximum abrasion resistance characteristics, and a minimum breaking strength of 130 lbs. Cord shall be of sufficient length equalized to properly control raising and lowering of blind and spaced not over 46" between cords.
Color of blind shall be selected from over 50 Levolor standard solid colors, Tiltone colors, specialties, or standard metallic slat finishes and complementary standard accessory finishes. DustGuard feature is not available on all colors.
