PART II - PRODUCTS
2.01 Manufacturer and Product Description
A. Acceptable product: Riviera LightMaster DustGuard 1" (25mm) blind
manufactured by Levolor Home Fashions.
- 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
- 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
- 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 18mm (nominally 16.7 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 .0075"+/- .0003
(prior to coating); after coating the thickness of the slats shall be
nominally .0085". Slats shall have a coating thickness of .8 mil to 1.5 mil.
Unperforated 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.
Slats shall be (select one):
- Pinlight - Slats shall be perforated with a nominally spaced pattern of
.039" diameter holes, nominally 13 per inch of slat length. Slats shall have
an openness factor of 1.5%.
- SheerView - Slats shall be perforated with a staggered pattern of .020"
diameter holes, nominally 177 per inch of slat length. Slats shall have an
openness factor of 6%.
- 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.
- Lift Cord Rout Hole shall be offset toward the back of the slat such that
it is completely covered by the overlapping slat when the blind is closed.
This will allow for total room darkening control.
- Color of blind shall be selected from over 190 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.
