The Hamilton Buhl 120" Diagonal Fixed Frame Projector Screen is a simple and effective way to set up a wall mounted projection system in your home or office. The uncomplicated design of this system makes for rapid assembly and hanging. Tension is provided to the screen from the tabs on to which the matte white screen fabric attaches. The sturdy aluminum frame holds the fabric firmly in place assuring an even, bright and crisp image. The borders are all trimmed in black and serve to both absorb any stray ambient light as well as help focus your audience's attention on the image.
