How it works: A left hand and right hand hinged panel assembly, each consisting of an integral side panel plus top panel, are hinged to a mounting strip. The mounting strip becomes attached to the outside of your laptop’s lid using pressure-sensitive Velcro strips (see sketch below). The assemblies overlap near the top center to form a 3-sided tunnel around the screen, approximately 7 inches deep.
The resulting tunnel blocks most light infiltrating around the top and sides of your screen. The panel assemblies can remain affixed to the outside of the netbook’s lid and swing nearly flat for storage.
Universal Fit: The unique, overlapping hinged panels allow width adjustments from 5.5 inches to 10.5 inches, to create a "perfect" fit for virtually all Netbooks, including many DVD players.
Quality Materials: The panels are made of ultra lightweight high density polyethylene, a highly durable, synthetic material that blocks 100% of light transmission.
Specification: Weighs only 3.5 oz. and adds only 1/8 inch thickness to laptop when folded close. All components are black.
