Product Overview:

The Mark I Cordless DustGuard Blind represents Levolor’s top quality blind for exposed headrail applications. Engineered for both durability and aesthetics, the Mark I   Cordless DustGuard Blind combines a valance-free headrail design with a concealed mounting system to provide an overall clean, finished look.

The DustGuard feature is a permanent paint process that disrupts the natural static attraction of dust particles to the slat. By removing the primary reason blinds attract dust, a 50-70 percent reduction in accumulation can be achieved. Less dust means less maintenance and a cleaner, more professional appearance.
The valance-free headrail is made of roll-formed corrosion-resistant Tomized steel and has a crowned underside profile to prevent light leakage. The working drum mechanism contains acetyl polymer bushings to reduce friction and provide smooth operation. The added feature of the concealed mounting system provides a clean finished look and eliminates the extra cost of an extruded pocket mullion. The bottomrail is fully enclosed with a color compatible bottom bumper designed to prevent marring of the windowsill and mullions.
The nominal .0085" thick slats are made of high grade magnesium aluminum alloy which provides superior strength and resiliency, guaranteeing a quality look for the life of the blind.The Mark I
DustGuard Blind has 15.7 slats per foot to insure tight closure and superior light control. The exclusive Guardian Tilter disengaging clutch mechanism eliminates over rotation of the tilt wand and protects the tilt mechanism against breakage.

The Mark I DustGuard Blind is offered in a large selection of popular colors and options. The SheerView perforation option provides a unique see-through feature, reducing solar heat gain up to 42% when compared to a fully opened blind while optimizing the exterior view and maximizing light/glare control.
