PART II - PRODUCTS

2.01 Manufacturer and Product Description

A. Acceptable product: LouverDrape MRRS Vertical Blind System manufactured by Levolor Home Fashions.

B. Materials:

  1. Headrail shall be of extruded anodized aluminum alloy 1-13/16" wide x 1-5/16" high for lift-out and 1-13/16" wide x 1" high for standard/recessed. Capped ends, provided with Delrin, or equal, sprocket wheels.
  2. Carriers shall be made of 7/16" wide Delrin plastic or equal and shall traverse on Delrin wheels. No glides or sliders shall be allowed. For top and bottom rail option, each vane shall be held in spring tension between a carrier in the top rail and a carrier in the bottom rail. For headrail only models, carriers shall have one-piece spur gear and a Delrin hook.
  3. Spacer links of flexible stainless steel 1/4" wide shall space and stabilize carriers by passing smoothly between stabilizer guides on each carrier.
  4. Vanes shall rotate 360 degrees and pack, when traversed, into no more than 7/16" per vane. When rotated, 2-1/8" vanes shall overlap not less than 1/4"; 3-1/2" vanes shall overlap not less then 3/8".
  5. Rotation mechanism shall consist of a #10 nickel-plated bead chain for dual rail option, or a #6 for headrail only models. The chain shall synchronize and actuate 360 degree rotation by turning a keyed aluminum rod actuating plastic worm and plastic spur gear in each carrier in both top and bottom rail. Gears shall provide no less than 10-to-1 mechanical advantage and keep vanes fixed until reset by control. No cord or 1-to-1 ratio mechanisms will be allowed. On top and bottom models, top and bottom gears shall be synchronized.
  6. Traversing mechanism shall allow vertical blinds to traverse left to right, right to left or split. Blinds shall traverse by means of a #10 beaded chain running in a Delrin sprocket rotating a traverse rod which is an anodized aluminum lead screw extending the full length of the headrail and actuating a lead nut.
  7. Cord Weight shall be of molded ABS plastic filled for weight. Cord weight shall be readily removable without detaching cord from headrail.
  8. End Caps: Control and return end cap assemblies shall be molded to match aluminum extrusion profile and provide contemporary aesthetic appearance.
  9. Installation Brackets shall be provided for overhead, surface or recessed installation using thumb clamps and angle brackets. Brackets shall be designed to facilitate installation and removal of track.
  10. Normal vane spacing on center is a fraction of an inch less than the vane size. For example:
      Vane width: 2-1/8" Spacing on center: 1-3/4"
      Vane width: 3-1/2" Spacing on center: 3-1/8"
  11. Vanes shall be selected from the following (select one): Control location and Stack Draw must be specified.

    a. Vanes shall be extruded of 100% GEON solid vinyl or equal. The vinyl shall also contain ultra violet inhibitors. Calcium carbonate content will not exceed 15% on standard colors. Vanes shall withstand 140 degree heat chamber for thirty minutes without distortion, and with no more shrink and stretch and 1/2 of 1%. A ten-foot vane suspended from the center of one end shall hang straight with no twist, warp or bow. Vanes shall be permanently flame resistant, if unaltered.

    Vanes shall be selected from the following:
    1. Nominally 2-1/8" wide. Perforated option available.
    2. Nominally 3-1/2" wide. Perforated option available.

An optional clip-on corrosion-free, nickel-plated steel chain shall be attached to weights to control swaying and keep unit functioning as a whole (if specified). Certificate of flame resistance must be provided.
    2. EverClear Louver Groover: Vanes shall be of colorfast fabric slit to appropriate width, slid into groover channel. Groover shall be extruded of 100% GEON vinyl or equal and shall be guaranteed not to crack or yellow for six years. Groovers should have clear edges that hold fabric in place.
