PART 2—PRODUCTS

2.01 VERTICAL BLINDS

A. Manufacturer and Product:

  1. Manufacturer: Springs Window Fashions LP
    a. Product: Graber G-98 Vertical Blind Headrail System.
    b. Options: (Describe)
    c. Color(s): Selected from Graber Vertical Sample Selector.

B. Product Description:

  1. G-98 Headrail Format:
    a. Track shall be roll formed 0.0190" thickness steel with baked on white gloss enamel. The headrail shall measure 1-51/416 inches wide and 1-11/48 inches high.
    b. Carrier body shall be molded acetal with a detachable carrier stem molded in clear non-yellowing polycarbonate. Carrier shall traverse on self-lubricated wheels to reduce draw force, and the carrier stem shall be replaceable without demounting the headrail. Carriers are located in the center channel making headrail reversible.
    c. Rotation of louvers shall be provided by pulling #6 plastic bead chain finished with tassels which rotates a gear assembly in the control housing. This drives an extruded (0.235 dia.) aluminum pinion rod passing through all carriers and transmits rotation to each self-aligning carrier stem through a molded worm gear and spur gear. The drive system shall rotate all louvers simultaneously a full 180 degrees with a 6-1 gear ratio and hold them in a fixed position until reset. A #6 nickel plated steel bead chain is optional.
    d. Spacing of louvers shall be achieved with a stainless steel spacer connecting each carrier body. Visually uniform louver spacing is provided when the blind is fully drawn. In the closed position, louver overlap shall be no less than 3/8-inch.
    e. Traversing shall be by means of a pulley system and a 1.8mm dia. traverse cord attached to the lead carrier. The self-lubricating cord pulley wheels of the drive-end shall rotate freely on their axles to allow for smooth traversing with a minimum draw force. The traverse cord shall have a minimum tensile strength of 125 pounds and a maximum stretch while in use not to exceed 1%. The cord shall be held down by a cord tension pulley that is attached to the floor, sill or jamb. The center spaced  louvers allow one way traverse installations to draw from right or left.
    f. Traversing: Optional headrail may be supplied without traverse cord for non-traversing blind.
    g. Stack Release: Feature is standard allowing for louvers to be moved away from control(s) ends for window cleaning.
     
  2. Louvers
    a. Louvers shall be selected from the Graber Vertical Louver Sample Selector. All vertical louvers shall be manufactured to exacting standards to resist fading, twisting and brittleness. Fabric louvers shall contain a bottom weight pocket sewn at the bottom with clear, poly thread. Each pocket shall contain one weight. Standard specification shall be no bottom chain for PVC, aluminum and fabric louvers. Optional specification shall be single bottom chain. NOTE: Bottom chain not available with fabrics inserted in groover .
    b. Sew-In Weight: Bottom weight is enclosed in pocket of fabric louver by sewing on three sides.
     
  3. Installation Brackets shall be provided to support the weight of the blind plus forces applied to operate the blind. Include hardware necessary for secure attachment of brackets to adjoining construction and headrail. Brackets shall be adjustable and designed to facilitate installation and removal of headrail.
     
  4. General: The blind shall be free of sharp edges, burrs or other defects which might be harmful. When other materials result in improved specifications, they may be adopted.
     
  5. Size Limitations for Cord Draw/Chain Rotation Controlled Blinds with 3-11/42" Louvers:
    a. Maximum width: 191"
    b. Maximum drop: 144"
    5a. Size Limitations with Channel Panel Louvers:
    a. Maximum drop: 120"
    5b. Size Limitations with 2" PVC Louvers:
    a. Maximum width: 157-11/44"

2.02 FABRICATION

A. Prior to fabrication, verify actual opening dimensions by on-site measurement. Calculate blind dimensions to fit within specified tolerances.

B. Fabricate blinds to fill openings from head to sill and jamb to jamb. The minimum clearance blind-to-blind shall be 11/44-inch minimum. Locate blind divisions at mullions.

C. Fabricate blinds to fill all exterior window openings except at doors, door sidelights and transoms unless noted.

Part 3 – EXECUTION

3.01 INSPECTION: Verify that the work area in which the blinds will be installed is free of conditions that interfere with blind installations and operations. Begin blind installation only when unsatisfactory conditions have been corrected.

3.02 INSTALLATION

A. Install blinds in accordance with manufacturer's installation procedure except as otherwise specified herein.

B. Install all brackets provided to prevent deflection in headrail.

C. Install blinds with adequate clearance to permit smooth operation of blinds and any sash operators. Hold blinds 1/8-inch clear from each side of window opening on inside mount unless other clearance is indicated.

D. Demonstrate blinds to be in smooth, uniform working order.

E. Store installed blinds in fully stacked position to avoid damage and accumulation of dust and dirt until such time that these conditions are eliminated.

3.03 CLEANING

If solid vinyl or aluminum louvers become soiled, wipe or sponge using a mild detergent and warm water solution. With fabric louvers, dust or vacuum with an upholstery attachment, for soil removal, sponge using a mild detergent and warm water solution (or a dry fabric cleaner) and blot dry. Do not immerse in water or dry clean.
