The Picture King Tripod Screen with Keystone Eliminator from Da-Lite is perfect for moving your presentations from room to room. The aluminum extruded legs will endure heavy use and transportation throughout your building or even off premises. The self-locking extension tube allows you to set the screen to accommodate any ceiling height. A toe-release mechanism at the tripod base offers a wide stance for maximum stability. This seamless, square-format screen has a matte white finish, ideal for situations with little ambient light. Black masking borders make projected colors seem bolder. Greenguard certified.
