Nationwide is pleased to offer the Monoblox AT64 Shift Screen system along with the full AV Stumpfl line. The truly revolutionary SHIFT screen system makes it possible for a single person to easily adjust a mobile projection screen‘s height, without having to disassemble it first. No extra measuring is needed to ensure the frame is level, due to a clearly marked height scale.  Available kitted with a screen or sold individually the SHIFT screen system legs can be combined with all existing AV Stumpfl mobile screen systems.

To adjust the screen height, one can start at the bottom of the scale and simply move the screen up to one‘s preferred position.
The SHIFT leg will lock automatically. To move the frame further down, one can just use the locking mechanism for releasing the frame. It is now possible to assemble a complete mobile projection screen system and then to adjust its‘ height in a matter of minutes.
